Preheat Oven to 350 degrees.
Grease and Flour a 9 x 9 square pan.
Toss in 4 Cups of mixed berries (bumble) Note: I use blueberry, strawberry, and blackberry.
Sprinke the berries with one half cup of sugar.
1 cup of warm milk that has been scalded with 2 teaspoons of lavender in it, and let it stand for five minutes.
Add three quarters of a cup of margarine, 1 cup of sugar, two egg yolks (save the whites), 1 teaspoon of vanilla, 2 and a half cups of unbleached flour, two teaspoons of baking powder, and three quarters of a teaspoon of baking powder. Set this batter aside.
Second Batter: Whisk two egg whites with a half cup of sugar until white and stiff (it takes patience and it helps if the egg whites are room temperature) when stiff, gently fold into first batter until suitably mixed and then pour on to berries. Bake 55 minutes and cool for ten minutes.
Optional glaze: which I never use, 1 and a half cups of icing sugar with two Tablespoons of cream, and 2 Tablespoons of margarine. Drizzle on.
I hope you enjoy this recipe as much as we have.
