Sofrito, a sautéed vegetable mixture that typically contains garlic, onion, and bell pepper, is used as a seasoning in much of Latin America and the Caribbean. Here, it flavors yellow rice. The color comes from annatto seeds—which have an astringent, slightly peppery flavor—heated in oil until bright red-orange.
Cooks' Note
You can substitute 1/4 teaspoon saffron for the annatto. Use only 1 1/2 tablespoon oil and crumble saffron into oil just before using it. Leftover annatto oil keeps, refrigerated in an airtight container, up to 1 month.
