This is, by far, the easiest thing to make; no heating or straining required. You simply mix fresh cream with some live-cultured buttermilk and allow it to sit out on the benchtop for 24–48 hours. That’s it! I can find a million uses for crème fraîche. I’ll often mix a bit into vinaigrettes to soften them or toss some into cream-based sauces or sweet whipped cream because I like the delicate acidity.

It is essential to find live cultured buttermilk to make crème fraîche. Be sure to read the label of the buttermilk you are buying. Substitute with live active kefir if you can’t find a cultured buttermilk.
If you wanted to even take this crème fraîche a step further, you could whip it in a freestanding electric mixer and make your own cultured butter.
