Last Friday, I stopped in to Reading Terminal Market to see Annelies and pick up a few things. While there, I wandered by the Fair Food Farmstand and commented on the gorgeous, fragrant strawberries. In response, the operations manager Anne, offered to sell me a flat of seconds*. Cheap.
I am unable to resist fruit bargains and so ended up walking the eight blocks home hugging a flat of berries. I found that people responded to the berries in much the same way they do when I’ve found myself carrying a new baby through a grocery store. They smile at your parcel and murmur under their breath, “Baby! (Berries!).”
I made it home, berries intact, and set my load down near the air conditioner to cool (there was no space in the fridge). There they sat until later that evening. When I finally started disassembling the flat, I discovered that these were true seconds and needed careful culling.
I put on a podcast and sidled up to the sink. I hulled and sliced, ruthlessly eliminating all the bits that moldy, slimy, or had started to smelly boozy. In the end, I had enough berries for some slow cooker strawberry butter (a batch of this, sweetened with cane sugar instead of maple) and a batch of low sugar strawberry vanilla jam.
I pureed the berries for the butter and set them up on low in my ancient four quart cooker to reduce overnight. I put the rest of the berries into a large bowl and pummeled them with a potato masher until I had about nine cups of pulp. That went into a eight quart pot with 2 cups of cane sugar and 2 split and scraped vanilla beans.
Now, had my refrigerator not been packed to the gills, I would have put the sugared berry mash in there and kept it cold overnight. However, there was no space in the inn, so I cheated a little. I brought it to a rolling boil for a couple minutes and then turned off the heat. I covered the pot, shoved it to the back burner, and left it there overnight.
Food safety experts might ding me for this practice, but the quick boil kills off the worst of the bacteria and the sugar acts as a preservative (plus, it was a relatively cool night. I don’t do this during the true heat of summer).
It was entirely fine when came back to it the next morning, and so I pulled the pot back to my most powerful burner, added 1 tablespoon of calcium water and the juice of 2 small lemons, and brought it back to a boil.
I boiled the fruit for 25 minutes (or so), until it had reduced by about half, was thickening up a little, and the worst of the foaming had subsided. I stirred 1 tablespoon of Pomona’s Pectin into 1/2 cup cane sugar and whisked it into the jam in a thin, steady stream so that the pectin didn’t clump.
Two more minutes of rapid boiling and it was done. The batch made 4 1/2 pints and I processed them in a boiling water bath canner for 10 minutes. The finished is sweet, but the primary flavor is strawberry. It’s a very good one for stirring into plain yogurt because it doesn’t overpower the pleasing tartness of the yogurt.
And remember, you can always treat this recipe as a template. You can add different flavors (strawberries with a little cinnamon and nutmeg is always nice). You can also slice the batch in half if 4 1/2 pints of a single flavor is more than you want in your pantry.
- 9 to 10 cups strawberry pulp
- 2 1/2 cups cane sugar, divided
- 2 vanilla beans, split and scraped
- 2 small lemons, juiced
- 1 tablespoon calcium water
- 1 tablespoon Pomona's Pectin
- Prepare a boiling water bath canner and enough jars to hold 4 1/2 pints.
- In a low, wide, non-reactive pot, combine the berry pulp, 2 cups sugar, vanilla bean seeds and pods, lemon juice, and calcium water.
- Set pot over high heat and bring to a rolling boil. Reduce heat to medium-high and cook at a vigorous boil for 20 to 25 minutes, until the volume has reduced by approximately half and the foaming has subsided.
- Stir pectin into the remaining sugar and stream it into the cooking jar, using a whisk to stir to help prevent clumps.
- Return the contents of the pot to an active boil and cook for an additional 2 minutes. Remove the pot from the heat.
- Funnel the jam into the prepared jars, leaving 1/2 inch headspace. Wipe the rims, apply lids and rings, and process in a boiling water bath canner for 10 minutes.
