When tomatoes are at their best, we recommend making the salsa roja. During the rest of the year (even in winter), tomatillos still have plenty of flavor and can be your go-to salsa base.
The keys to this fast, simple dish, which was inspired by a crab-stuffed tomato at Yves Camdeborde's Paris brasserie, Le Comptoir du Relais, are ripe tomatoes, fresh herbs, and excellent crabmeat.
