Small Batch Roasted Tomatillo Salsa

a pound and a half of tomatillos

Back when this blog was a wee fledgling, just finding its feet, I posted a recipe for oven roasted tomatillo salsa. It was one I learned to make by watching a woman named Teresa (for a handful of months, we were co-workers of sorts). Most of the time, when I find myself in possession of a small amount of tomatillos, I make some variation on this salsa and remember those days when I was fresh out of college and still trying to figure out what the heck I was going to do with myself.

halved tomatillos

The one problem with that first recipe was that it wasn’t designed for canning. I’ve gotten more emails than I can count over the years, asking me whether it could be canned and I always had to say no. However, it feels like a hole not to have a recipe on this site for a water bath safe tomatillo salsa (happily, there’s one in the cookbook, so I’ve not entirely neglected my duties).

roasted

When I found myself in the kitchen with a pound and a half of tomatillos earlier today, I determined that it was the perfect moment to come up with a very small batch of water bath safe tomatillo salsa. I used the tomatillo salsa recipe on the National Center for Home Food Preservation website as a starting point and then adapted.

In the end, I essentially divided the recipe by five and omitted a few low acid ingredients. I skipped the green chiles and hot peppers with a single jalapeño that had been sitting in the fruit basket so long that it had turned red. I increased the volume of tomatillos a little to replace the missing chiles. I added a tablespoon of minced cilantro. And I kept the levels of additional acid constant.

For those of you who feel uncomfortable with me altering a tested tomatillo recipe in this manner, I point you in the direction of this abstract. It details pH testing of tomatillos and reveals that their pH was found to be consistently below 4.1. That is well below the cut-off of 4.6 pH. What’s more, that study also found that pH levels remained in the safe zone when tomatillos and onions were combined and at least 50% of the volume of the jar consisted of tomatillos.

After roasting the tomatillos, I had approximately 1 3/4 cups of pulp. To make this salsa, I combined that acidic tomatillo pulp with approximately 3/4 cup of low acid ingredients (onions, garlic, cilantro, 1 jalapeno, and a little ground cumin) and the acidified with three tablespoons of bottled lime juice (my starting recipe used 1 cup and yielded 5 pints. My recipe was appearing to yield about 1 pint. There are 16 tablespoons in a cup, so I divided that by 5 to arrive at 3 tablespoons). My single pint of yield was more than 50% tomatillos by volume and contains a great deal of additional acid.

The combination of the tomatillo concentration and the added acid makes me feel entirely comfortable processing this salsa in a boiling water bath. However, the recipe makes just a pint (with a few spoonfuls leftover for immediate eating). If you’d prefer, you can always just pop it in the fridge and eat it up over the course of the next week or two. Up to you.

Small Batch Roasted Tomatillo Salsa

Ingredients

  • 1 1/2 pounds tomatillos
  • 3 garlic cloves
  • 1/2 cup minced onion
  • 1 jalapeño, seeded and roughly chopped
  • 3 tablespoons bottled lime juice
  • 1 tablespoon minced cilantro
  • 1 teaspoon sea salt
  • 1/2 teaspoon ground cumin

Instructions

  1. Preheat oven to 400 degrees F.
  2. Remove husks from tomatillos and rinse to remove their natural sticky residue.
  3. Cut the tomatillos in half and place them face-down on a rimmed roasting pan. Add unpeeled garlic cloves to the pan and place in the oven. Roast for 15 to 20 minutes, until they release a goodly amount of liquid and the tops are developing light brown spots.
  4. Remove pan from the oven. Collect the roasted garlic cloves and set aside.
  5. Scrape the tomatillos and their juice into a blender carafe. Peel the garlic cloves and add them to the blender, along with the onions, jalapeño, lime juice, cilantro, salt, and cumin.
  6. Blend at a moderate speed, until the tomatillos are broken down and the other ingredients are just integrated (you should still be able to see small specks of green from the cilantro).
  7. Pour the smooth-ish salsa into a small saucepan and bring to a boil.
  8. When salsa is pipping hot all the way through, pour it into a prepared pint jar (or two half pints, if you prefer).
  9. Wipe rims, apply lids and rings, and process in a boiling water bath canner for 15 minutes at sea level (adjust your processing time if you live at higher elevations).
  10. When time is up, remove jar(s) from canner and set on a folded kitchen towel to cool.
  11. Wait 24 hours and test the seal(s). If the seal(s) are good, jars are shelf stable for up to one year.

    I made your tomatillo salsa recipe from the cookbook the other day and was considering roasting the tomatillos, onions & peppers on my next go round. I also made a tomatillo mango salsa and have been trying to figure out if I could hot water bath can it or not. It seems like I could, but I definitely do not want to chance it.
    What I love about tomatillos is that you can pop them in the freezer straight from the garden and pull them out, roast them and go with them at any time.

    This looks fabulous. Tomatillo salsa is on my list to try. Is there a ‘season’ for tomatillos? I live about an hour west of Philly (we’re sort of neighbors?) so I know we don’t grow them locally.

      Marisa says:

      Tomatillos are in season right now (they grow during the same season at tomatoes). I’m surprised that no one is growing them out in your area, because the Pennsylvania summer climate is perfect for them.

    Marisa, can we just buy a pH meter and stick it in our jars? How is pH tested, and why can’t we do it at home in a safe and effective way?

    Misha says:

    This is good to know. I have another tomatillo recioe I make (and freeze). My concern was if roasting fruits and vegetables altered the pH in any way so I couldn’t count on the numbers. Any ideas before we start fooling around woth ingredients?

    Thanks, Marisa!
    I canned my first salsa verde last summer using bunches of tomatoes from the CSA farm share and freshly roasted Hatch chiles from the grocery store down the road. This year, probably due to our cooler, wetter, Ohio summer, the Hatch chiles came earlier than the tomatillos so I put them up in the freezer, and I’m getting smaller amounts of tomatillos about every other week in the share. I’m glad to have a small batch recipe, and excited to try roasting the tomatillos now that it’s cool.

    Tomatillos are the Energizer Bunny of my garden. I planted 3 plants and bet I have harvested nearly 30 lbs from them. And they are still going. With this kind of yield from my plants, I have only one thing to say about a recipe for one pint – “ain’t nobody got time for that.” lol I simply went nuts with the recipe on the NCHFP site, but it is good to know some modifications can be made. I will study your ratios and make some adjustments.

      Marisa says:

      Sadly, I have no such tomatillo source, so a single pint is going to have to do it for me. I’m seriously jealous of your three plants, because this salsa is good!

      • Linda Higgins says:

        I just bought 2+ pounds of tomatillo’s at my local Mexican market. They were 3#s for .99.
        I mix the tomatillo’s with green tomatoes , hot peppers, cilantro and onions. Yummy, but wanted to can some 4oz jars for Christmas baskets. This is good timing! Thanks.

      • James says:

        Sadly, tomatillos need two separate plants to pollinate.

    Are jalapenos and green chiles the same Ph? I am wondering if I can sub one for the other entirely. My family cannot tolerate the spice of jalapenos but I LOVE tomatillo salsa and I would love to make a mild version.

    • 9.1
      Marisa says:

      You really don’t get much spice from a single jalapeño. I don’t know if the two have interchangeable pHs. And I really only used about 1 1/2 teaspoons minced jalapeño, so that wouldn’t give you much green chile.

    Kathy says:

    Yay! This sounds great – my farmers market should still have tomatillos this weekend. In my gut, it seemed that your old recipe would have been safe for canning – I was going to get a ph tester or some litmus paper (because it’s that good). Stil might, but so glad to have this confirmed.

    Do you ever pressure-can? I just got a pressure canner this spring and have been LOVING and haven’t used my water-bath at all this summer. I also love all the low-acid stuff I can can in it.

    I’ve never thought of preserving tomatillos – even though they grow well around here, no one sells them cheap enough or in bulk enough for me to do more than a batch of salsa for nachos and beans for a week. I have the end of the jar in the fridge right now, waiting for lunch tomorrow!

    • 11.1
      Marisa says:

      I do pressure can occasionally. I have the smallest pressure canner you can get, but it totally dwarfs my stove, so I only pull it out for the low acid stuff. So glad you’re loving yours, though!

    Martha says:

    This sounds good. Can you really freeze fresh tomatillos and roast them later as Becky wrote? What a great idea. I could do the salsa later and still have tomatillos available!

    I do need help with another project. I have 8 quarts of ground cherries and no idea what to do with them. I am told they are a relative of the tomatillo. When the husks are removed they will measure near 1/2 of the original-or near 4 quarts. Any suggestions?

  13. 13
    Martha says:

    Thanks, Mary. I will check that site. Ground cherries are about the size of a cherry, but look like tomatillos. The fruit grows in the same kind of husk as a tomatillo, but they are yellow when ripe. This is my first encounter with them. I got them in the Amish area of Illinois. I guess they are an obscure or forgotten fruit.

    Hi, can I do this recipe with green tomatoes? I cannot get tomatillos, but the look of the jar and the green colour are very tempting. Many thanks.

    Karla says:

    If I’m using a recipe of my own for salsa, I use pH paper and make sure it reads about 3, which means a proton concentration ten fold higher than a pH of 4, to account for possible inaccuracy. It’s not hard to get it to that with lime juice (for a salsa verde) or vinegar (for a salsa brava). That said, I use the method only for thin, pureed salsas.

    Suzannah says:

    I usually make salsa verde with green tomatoes. Would that be okay
    in this recipe for canning? Here in Maine, green tomatoes are plentiful…
    tomatillo’s not so much.

      Marisa says:

      I’ve not tried it, but I know that the National Center for Home Food Preservation does say in some of their tomatillo recipes that you can swap in green tomatoes.

    Joy says:

    I am always in awe at the amoutn of scientific work that goes into your recipes. Thank you so much for taking the time to explain HOW you determine the safe levels of acidity in your recipes. It gives me much more confidence when producing something to know that it is scientifically backed, and having not canned very much for too many years, I don’t have that type of skill set. Thank you for giving me a jumping off point to start, you are such an inspiration!

    I have your cookbook and love it. In fact, I just made some pickled carrots (without daikon) today! This evening I was searching around for blogs about canning (mostly looking for pictures of all the goodness everyone is preserving this time of year) and I stumbled upon your website. I’m so thrilled to see the updates and it is perfect timing for this post on small batch tomatillo salsa as my husband prefers the roasted to raw and I didn’t think I had quite enough in the garden for a big batch. Thanks! I’ll look forward to reading back through your posts and website!

    I just made my second batch yesterday from home-grown tomatillos. I had never grown them before but they did great (about 5lbs from just 2 plants!). I used a recipe from Rick Bayless for the second batch-a spicy oven-roasted version that I froze. It’s yummy!

    Hafiz says:

    I am so glad I found you ; ). I have a very silly question…I am one of those guys in your post who is interested in pickling all on a sudden. I pickled 7 pounds of green tomatoes, however after I got them out of their water bath they didn’t pop. So, I turned them upside down on the table, and then I flipped them over and I was checking the lids (within 5 min – I know I should have just waited longer). As I pressed each lid, they popped and stayed down. I undid the ring and tried to lift up the lid with my fingers and it seemed pretty solid. Am I ok with these 7 pounds of pickles…or am I in a real pickle here : )?

    Any good recipe for a green onion pickle as well as a swiss chard stem pickle?

    Thanks so much!!!

    […] It’s been raining cats and dogs.  Preserving activities are feeling more fall-like.  A failed batch of butter and my remaining cache of chanterelles yielded 42 half pints of sautéed mushrooms for pizza or maybe at least a cup of mushrooms a week for some yet to be thought of meal.  That about stuffed the freezer full, and my pork is coming soon. Ugh. Tomorrow I am going to tackle the tomatillos I think, thanks to Marisa I will can the salsa instead of freezing it using this recipe. […]

    […] After an amazing trip to Mexico we were definitely in the groove for some more spicy food. We came home and made this wonderful salsa verde. We also made sriracha sauce and hot sauce. We liked the salsa verde so much that I tweaked the recipe a little and canned more of it for later. I swapped out the fresh lime juice for bottled lemon juice and adjusted the volume of onions and cilantro using the guidelines here. […]

    Heather says:

    I like the simplicity of your recipe. I sounds relish. Is it possible to use fresh lime juice and not bottled? I don’t think I will can it if I make a small batch. I have previously read that if you are canning to use bottled though. I don’t think I will this batch though.

    • 29.1
      Marisa says:

      If you don’t want to bother with the canning step, feel free to use fresh lime juice. It’s only necessary if you’re going to run it through a boiling water bath.

    Just wanted to say I canned FOR THE FIRST TIME EVER last night and made this recipe. I’m so proud of it and happy with the whole process. Can’t wait to taste and share it with my coworkers today for lunch!! Thank you so much for what you do and can’t wait to make more of your recipes! I keep looking at my half pints proudly.

    Julie says:

    This works great with green tomatoes for anyone who doesn’t grow Tomatillos. I used a pressure canner, but with all the additional acid, I’m sure water-bath canners work fine, when in doubt, just keep it in the water-bath canner longer, or freeze. Great recipe!!

    jenna says:

    Do you have to use bottled lime juice? Is there a reason there having to do with more consistent acidity levels or could I use fresh? Thanks!
