1 tbsp unsalted butter
1 1/2 pounds of berries (your choice), washed and picked over
3 tbsp all-purpose flour
Pinch of salt
1/4 cup granulated sugar
4 large eggs
2 large egg yolks
1 cup of milk
1 cup of heavy cream
1 tsp vanilla extract
1) Preheat the oven to 375 °F. Butter a 10-inch porcelain tart dish, and fill with berries. Set aside.
2) Sift flour and salt together into a large bowl. Add sugar.
3) Whisk together whole eggs, egg yolks, milk, cream, and vanilla.
4) Using a sieve, strain the batter over the berries. Bake until puffed and browned, about 45 minutes. Let cool until warm; it will sink slightly.
