Serves 2
Active Time:50 min Start to Finish:50 min

For egg salad
1 hard-boiled large egg, finely chopped
2 tablespoons sour cream
1 tablespoon finely chopped chives

For blini
2 tablespoons buckwheat flour
3 tablespoons all-purpose flour
1 teaspoon sugar
1/8 teaspoon baking soda
1/8 teaspoon salt
1/4 cup whole milk
1 large egg, separated
1/2 stick unsalted butter, melted and cooled, divided

For filling
1/4 lb thinly sliced smoked salmon at room temperature
2 oz trout caviar, such as rainbow–trout caviar*, or salmon roe
Garnish:sour cream; chopped chives

Make egg salad:
Stir together all ingredients and a pinch of salt.

Make blini:
Whisk together dry ingredients in a bowl. Add milk and yolk and whisk until smooth.
Beat egg white with a clean whisk in another bowl until it just holds soft peaks. Fold into batter along with 2 tablespoons melted butter.
Brush a 12-inch nonstick skillet with some of remaining melted butter, then heat over medium heat until hot. Working in batches of 6 or 7, drop 1 level tablespoon batter per pancake into skillet and cook until bubbles appear on surface and undersides are golden, 45 seconds to 1 minute. Flip over and cook 1 minute more. Brush blini on both sides with some of remaining melted butter, then transfer to a plate and keep warm, covered with foil. Brush skillet with butter between batches.

Fill tortes:
Drape smoked salmon on 6 blini and top with egg salad. Spoon caviar onto 6 more blini, then stack on egg-salad-topped blini.
