Cornish Heavy (Hevva) Cake

Preheat the oven to 190°C. Line a medium, square cake tin.

Rub the butter into the flour until it's the texture of fine breadcrumbs. Add the sugar and fruit and mix well. Add the milk and mix to a soft, stiff dough.

Press into the cake tin, pushing down firmly in the corners. Score the top of the cake with a sharp knife, making criss-cross diagonal lines.

Place in the middle of the preheated oven and bake for 35-40 minutes, or until golden brown and a skewer inserted in the middle comes out clean.

Remove from the oven and while still warm, brush with milk and give a generous sprinkling of granulated sugar. Allow to cool and cut generous slices.
