Black bean soup
Easy black bean soup is a thick, smoky bowl made from canned beans. Onion, garlic and cumin build the flavor. Mashing some of the beans makes it creamy without any cream. Lime, cilantro and yogurt finish it in about 25 minutes.

The science: why this works
Why mashing the beans thickens the soup
Beans are full of starch and fiber. Mashing about half of them against the pot releases that starch into the broth, which thickens the soup naturally and leaves some whole beans for texture. No flour or cornstarch is needed, which keeps the recipe simple.

Spice flavors dissolve in oil more than in water. Stirring the cumin, garlic and chili flakes in hot oil for 30 seconds spreads their taste evenly and avoids a raw spice flavor. Heat also drives off the harsh, dusty edge that raw spice powder can have.

Beans are earthy and rich. Lime juice adds acid that cuts through the heaviness and wakes up the other flavors. A little goes a long way. Salt and acid work together, and a pinch of each wakes up a dish.
