Serves 4 as a side.

2 limes
2 tomatoes, finely chopped
2 tablespoons sour cream or crème fraîche
2 ripe avocadoes, peeled and pitted
Salt
Fresh cilantro, roughly chopped, for garnish

1. Juice the limes into a bowl. Add the tomatoes, sour cream or crème fraîche, avocados, and salt and mash it all up with a fork or the back of a spoon. You want to leave it lumpy, not blender–smooth.

2. Season with more salt if needed, then sprinkle the cilantro on top. Yum.
