½ cup dried black beluga lentils, rinsed
2 cups water
2 pieces kombu (dried seaweed, about 2 inches by 2 inches)
1 tablespoon sea salt
1½ tablespoons highest-quality extra-virgin olive oil
8 ounces Yukon Gold potatoes, peeled and coarsely chopped
1 teaspoon water
1 tablespoon unsalted butter
½ cup flour
2 teaspoons baking powder
½ teaspoon sea salt
1 teaspoon sugar
1 large egg
1 cup whole or low-fat buttermilk
Canola or other vegetable oil, for frying
½ cup creme fraiche (may substitute low-fat sour cream or Greek-style yogurt)
Coarse sea salt (optional)
¼ cup chopped fresh dill
For the "caviar": Rinse the lentils. Combine them with the water, kombu and salt in a small pot over medium-high heat. Bring to a boil, then reduce the heat so the mixture is barely bubbling around the edges; cover and cook until the lentils are just tender, 20-25 minutes. Allow the lentils to cool in the liquid.
Discard the kombu, then drain the lentils and stir in the olive oil.
For the blini: Combine the potato, water and butter in a microwave-safe dish; cover and microwave on HIGH for 6 minutes, until the potato is tender. Cool.
Combine the flour, baking powder, salt and sugar in a large mixing bowl. Whisk together the egg and buttermilk in a small bowl.
Run the cooled potato mixture through a ricer into the bowl with the flour mixture. (Or mash very thoroughly with a potato masher or fork.) Whisk the egg-buttermilk mixture into the flour-potato mixture.
Pour 1 tablespoon of canola or vegetable oil into a large skillet over medium heat. Once it shimmers, add batter 1 tablespoon at a time to form small pancakes. (You'll be able to fit about 5 blini at a time in a 12-inch skillet.) Cook until bubbles form all over the blinis' surface and the blini are deeply browned on one side, 2 to 3 minutes; carefully flip and cook on the second side, then transfer to a plate. Working in batches, cook the remaining blini, adding oil to the pan between batches if it looks dry.
To assemble: Top each blini with creme fraiche and a teaspoon of beluga lentils. Sprinkle with coarse sea salt, if desired, and with fresh dill.
Serves six to eight (makes 24 to 30 blini).
