This dish comes from the Grampians--the Scottish moors famous for grouse hunting. The strawberry sandwich may be compared to the American strawberry shortcake. Either way, it's delicious!
Recipe: Traditional Scottish Cookery
Grease and line with parchment paper the bases of two 8-inch baking pans.
With an electric mixer, beat egg whites until stiff. Whisk in the egg yolks one at a time, whisking well after each addition until stiff. Whisk in the caster sugar, water, and a few drops of vanilla extract.
Gently add the flour and baking powder, folding with a metal spoon. Turn mixture into the prepared pans and level them out with a spatula.
Bake in a preheated 350-degree oven for 20-25 minutes until risen, golden, and the centers spring back when touched lightly.
Cool slightly, then turn out onto a wire rack; remove the paper and leave to cool.
Whip the heavy cream until peaking. Mash the strawberries, reserving several for slicing, together with 2 Tbsp. of the powdered sugar and a few drops of vanilla extract. Sandwich between the two cakes. Sprinkle with remaining powdered sugar and garnish with some strawberry slices.
