: Sauce: Place berries and jam in a small saucepan. On low heat, simmer for 2-3 minutes. Remove from heat, stir in vanilla. Reserve.
2
: Preheat oven to 450ºF (232ºC). Place butter in a 10” (25cm) heavy ovenproof frying pan. (You can also use a 10”/25cm pie plate or baking dish). Place pan in oven until hot and butter is sizzling (about 8-10 minutes).
3
: Batter: While your pan is heating up prepare batter. Beat eggs until light and frothy. Add remaining ingredients. Beat until batter is smooth, about 3-5 minutes.
4
: Carefully, using a pot holder or oven mitt remove hot pan from oven. Immediately pour batter into pan and return to oven. Bake for 20-25 minutes until puffed and golden brown.
5
: Remove from oven. Puff will start to deflate after being removed from oven. Serve right from the pan or place on a serving dish. Top with berry sauce, sprinkle on fruit, sprinkle with icing sugar, cut into wedges and serve immediately. Puff will deflate.
