In a small saucepan, combine berries, sugar & 1 tsp lemon juice; heat until bubbling. In a separate dish, combine cornstarch & water; pour into berry mixture. Stir until thickened & remove from heat.
Pudding Cake
Preheat oven to 350 F. Butter 6 ramekins (or a 10-inch glass dish). Divide the saskatoon compote between the ramekins; set aside.
Grate 1 Tbsp of lemon zest. Squeeze 1/3 cup lemon juice. Set aside.
In a bowl, whisk together flour, salt & 2/3 cup sugar. In another bowl, whisk together YOLKS, milk, lemon zest & juice. Add to the flour mixture; whisk until completely blended.
In a bowl, beat WHITES until soft peaks form; add the 1/4 cup sugar slowly & beat until medium peaks form. Whisk 1/4 of the whites into flour mixture; our this mixture over the remaining whites. Whisk together using a folding technique to keep from deflating egg whites.
Pour the batter into ramekins & place them into another larger pan. Fill the bottom pan with water as high as it can go without floating the ramekin dishes.
Bake for 25-30 minutes depending on the size of ramekin dishes. Serve warm or at room temperature.
Recipe Notes
I flipped my little puddings over so all those pretty saskatoon berries could sit on top.
