Pre heat the oven to 400 F.
Take all the ingredients for the fruit in a mixing bowl – berries, cornstarch and sugar. Toss to coat everything. Transfer it in a baking dish or 4 medium sized ramekins.
Once the oven is hot, place the baking dish or ramekins on a baking sheet (to catch any juices overflowing dripping outside) and place it in the oven for about 20 -25 minutes.
Make the biscuit layer.
Mix all the dry ingredients in a mixing bowl- all purpose flour, almond meal, salt, sugar, cardamom powder and baking powder. Give dry ingredients a stir.
Cut cold butter into the flour mix with the help of your hands until it resembles pea sized crumbles of flour and butter.
Add in the buttermilk and vanilla extract and mix all together to form a rough shaggy dough. Do not over mix the dough.
Remove the fruits from the oven, using an ice cream scoop or hands, scoop out few dollops of dough on top of the fruits covering the berries. Do not worry about placing it exactly in some design. Just make sure everything is covered.
Put the baking tray back in the oven and bake until the top of the biscuits looks brown on top and they have risen a bit for about 20-25 minutes.
Remove it and let it cool down for 15 minutes before serving.
Serve with a dollop of vanilla ice cream or crème fraiche.
It can be stored in the refrigerator covered with foil for few days. It tastes better when served immediately after baking.
