The deliciousness of butter is a universally understood truth (and the primary reason for Paula Deen’s career). However, for as good as regular old butter can be, cultured butter is just that much better. Cultured butter is made from cream that has been doctored with a culturing agent, allowed to sit out for a bit and develop tasty, tangy bacteria.
Now, cast your minds back a couple of months to when I wrote about making creme fraiche. To recap, it’s a process in which you stir some buttermilk (culturing agent) into a jar of heavy cream (not the ultra-pasteurized stuff) and let it sit out until it develops a host of tangy bacteria. Do you see where I’m going here? That’s right! Once you’ve made creme fraiche, you’re about 15 minutes away from homemade cultured butter. Let’s walk through the steps, shall we?
Pour your creme fraiche into the bowl of a food processor. I started with approximately 20 ounces of very thick, tangy product. Tighten the lid of the process and run the motor for 2-5 minutes.
It only takes about 2 minutes in my food processor, but I’m certain your times will vary. You want to process it until it looks like the picture above. You should have a thin, visible liquid with clumps of butter spread throughout. Do know that the liquid will be thicker than when you make butter from uncultured cream.
Place a fine mesh sieve over a bowl and pour the butter and whey through the sieve. Make sure to save that whey, it’s incredibly flavorful and I’ll be posting a baking recipe for you guys that will detail how to use it later in the week. Using the back of a rubber or silicone spatula, gently move and scrape the butter in the sieve to help remove more of the whey. You will find that a bit of butter pushes through the sieve, just scrape it off the bottom and plop it back into the bowl of the sieve.
When most of the visible whey has been released, remove the bowl from underneath the sieve. Rinse the butter with the coldest water your tap can produce and repeat the pressing and draining of the butter (still without the bowl). The goal is to remove as much of the whey and water from the butter. The more whey you can remove, the longer the shelf life of the butter will be.
After several rinses, place the butter in a shallow bowl (I love this wooden bowl for this job) and work it some more, still attempting to work any remaining whey out of the butter. If you like a salted butter, this is the point where you can sprinkle in a pinch or two of fine grain salt. Mix it into the butter thoroughly with the spatula. In addition to the flavor boost the salt gives, it will also extend the shelf life of the butter a bit.
When your butter is a smooth and whey-free as you can manage, pack it into a small jar (I got enough to exactly fill an 8-ounce jar with this batch). Pour the reserved whey into a container (I love this milk jug I brought back from Portland a couple of years ago for this sort of thing). Both should be stored in the fridge.
Cultured butter is amazing stirred into polenta, dabbed on warm muffins or slathered on toast. Once you make it, you’ll find yourself inventing reasons to eat it.
