Before cooking, remove the crab shelves and set them to defrost (keep the sticks at room temperature until soft) so that the sticks unfold well and do not break or tear. Boil hard-boiled chicken eggs, cool and peel. Rinse the greens and dry with a paper towel or napkin. Place the sprats on a napkin to drain excess oil.
Grate the eggs on a fine grater into a deep plate. Finely chop the dill and add to the plate to prepare the filling. Add cream cheese and mayonnaise so that the mixture is not too thick. Stir the mixture well and squeeze out 1 clove of garlic. Add salt to taste, if necessary, and mix thoroughly again.
Carefully unfold the crab shelf, being careful not to tear it, and carefully place a thin layer of filling on the inner surface with a teaspoon. Place sprat on top of the filling closer to the edge. Carefully roll the crab stick with the filling and sprat into a roll.
In the same way, form rolls from the prepared ingredients. Place on a plate, cover the resulting rolls with cling film to prevent chaffing. Serve the appetizer cold.
To serve, place the rolls beautifully on lettuce leaves, and when serving for the holiday, garnish with herbs and lemon slices.
