Step 1In a small saucepan, heat the milk over high heat just until it comes to a good simmer (do not let it boil), then remove from heat and cool the milk to lukewarm.
Step 2While the milk is cooling, sprinkle the yeast over the warm water, then stir to combine. Set it aside until it dissolves and begins to bubble, about 5 minutes.
Step 3In a medium bowl, sift together the flours and 1/2 teaspoon salt, and make a well in the center. Add the yeast mixture and 1 cup of the warm milk. Slowly incorporate the flour into the liquid with a spoon or your hands, gradually mixing it in to form a smooth batter. Beat the batter for 1 minute to fully incorporate the ingredients. Cover the bowl loosely with plastic wrap and set it aside to rise until the batter is full of bubbles and light in texture, 2 to 3 hours.
Step 4Roast the pepper over high heat on top of a stove burner, turning with tongs until the skin is completely charred. Alternatively, toast under a broiler on all sides to char. Place the pepper in a plastic bag, and loosely cover to allow steam to loosen the skin. When cooled, peel and halve the pepper, discarding the core and seeds. Slice the pepper crosswise into one-eighth-inch strips. Set aside.
Step 5When the batter is light and bubbly, stir in the yolks and one-half cup of the milk. The batter will be elastic but should pour easily (if not, add more of the milk as needed). In a separate bowl, whisk the whites until they hold a soft peak; gently fold into the batter.
Step 6Heat a large frying pan over medium heat. Add 2 to 3 tablespoons butter and heat until the butter is melted and has stopped foaming. Ladle the batter into the pan to form 3-inch blini (about 2 tablespoons of batter per pancake) and cook until the tops are bubbly and the undersides browned, 1 to 2 minutes. Flip the blini over and cook the other side, about 1 minute. Place the blini on a plate, stacking them to keep them moist. Repeat until all the blini are cooked, using more butter as needed. This recipe makes 3 to 3 1/2 dozen blini. (Recipe can be prepared up to this point a day ahead. Place the cooked blini in an airtight container and refrigerate.)
Step 7Before serving, warm the blini in the microwave or in a 350-degree oven, wrapped in foil, for 15 to 20 minutes. Spread each pancake with a spoonful of tapenade and top each with 2 crossed strips of pepper. Plate 3 per serving.
Step 1In a medium bowl, soak the torn bread in the cold water for 5 minutes. In the bowl of a food processor, combine the garlic, olives, anchovies, almonds and capers. Drain the bread, squeezing out the excess water, and add to the other ingredients. Pulse the mixture until coarsely chopped. With the processor running, gradually pour in the olive oil and continue working to a medium puree, about 1 minute. Stir in the lemon juice and pepper to taste. Add additional seasoning as desired, though the tapenade should be salty enough.
