This lovely moist and tangy family cake is also great made with blueberries or raspberries.
- Sieve the flour, salt and baking powder into a large bowl. Rub in the fat until it resembles breadcrumbs and then add 110g of sugar. Beat together the egg, milk and lemon rind (save a little for the topping), and then stir into the dry mixture until you have a thick batter.
- Rinse and dry the blackberries on paper towel then halve any very large ones. Preheat the oven to 180C/350F/gas Mark 4.
- Pour a good half of the mixture into a lined and greased 15-17.5cm loose-bottomed tin. Sprinkle on half of the blackberries, the rest of the batter and some more blackberries and sugar.
- Bake for about one hour until firm and golden. Sprinkle with remaining fruit, lemon rind and sugar, and leave to cool in the tin.
