Vinegar Cake
Instructions
1. Grease a deep 23 cm (9 inch) round cake tin.
2. Rub the butter into the flour until the mixture resembles fine breadcrumbs, then add the fruit and sugar. Sprinkle the bicarbonate of soda into the milk, then add the vinegar. This will froth up. While it is still foaming, add it to the dry ingredients and mix in well.
3. Turn the mixture into the prepared tin and bake at 200°C (400°F) mark 6 for 30 minutes, then reduce the oven temperature to 170°C (325°F) mark 3 and bake for another 1 1/2 hours or until firm to the touch. If the top gets too brown, cover with paper. Leave to cool in the tin for 30 minutes, then turn out on to a wire rack to cool completely.
