A simple sauce made of lemon, capers, and butter can liven up any dish. The rich butter pairs well with the bright tartness of the lemon and the umami brininess of the capers.
Best of all, the sauce takes mere minutes to cook. Melt 3 or 4 tablespoons of butter in a pan, add lemon and a few teaspoons of capers, and simmer it for a minute or two.
Once the sauce emulsifies, finish it off with a pinch of salt. You can experiment with your ratios for a richer or tangier sauce, or cook it for longer for a thicker texture.
Use the sauce on meat and seafood dishes that need extra flavor, serve it over plain roasted vegetables like broccoli or asparagus, or let it work its magic on any side dish.
