For the blackberry and curd casserole, mix the butter and curd well, add 1 egg and 1 tablespoon of sugar, and then add the breadcrumbs and blackberries.
Spread butter and breadcrumbs on a baking dish, pour in the mixture and bake over medium heat until golden brown.
Preparation Tip:
You can also make a casserole with other berries instead of a blackberry and curd casserole.
