A homely, but intensely flavored, blackberry dessert which does a good job of softening the crunchy bits.
Wash the blackberries and drain. In a small saucepan (lid ajar), cook blackberries in water for 5 minutes. Meanwhile combine the sugar, cornstarch, and salt in a large custard cup.
Add sugar mixture to blackberries and stir until thickened and translucent. Cook another 5 minutes, stirring occasionally to keep the mixture from sticking.
Remove from heat and add lemon juice. Let sit for 5 minutes.
Serve with thick cream to swirl in.
Serves 2
