There are a lot of ways you can play around with this — flavoring the sour cream with lemon, vanilla, cinnamon or almond; using a mix of berries, etc. — but it is flawless the way it is. Want to fancy it up for fancy people? Make it in individual ramekins or tiny gratin dishes.

[Updated to add] Ooh, I just had an idea — Swap thick, full-fat Greek-style yogurt swapped for sour cream and serve it at a brunch to what I have to imagine would be a round of applause. Or at least I’d applaud.
