Souffled Black Bean Canapes

Preparation

1. Step 1

   Preheat broiler. Lightly toast the baguette rounds and arrange them on a foil-lined baking sheet. Alternatively, arrange the tortilla chips on a baking sheet without toasting them.

2. Step 2

   Place the black beans in a food processor and process until finely pureed. Add the chili powder, cumin and lime juice and process until mixed. Transfer this mixture to a bowl and season to taste with salt.

3. Step 3

   Beat the egg whites with a pinch of salt until they hold firm peaks but are still creamy. Stir one-fourth of the egg whites into the black bean mixture, then gently fold in the rest.

4. Step 4

   Spoon some of this mixture onto each bread round or chip. Place under the broiler until just firm to the touch and lightly browned.

5. Step 5

   Arrange the canapes on a serving platter, spoon a small dab of sour cream on each and serve.
