I have the book and here's the recipe.
60g butter
200g plain flour
2 teaspoons baking powder
half teaspoon bicarb of soda
150g caster sugar
quarter teaspoon salt
juice and finely chopped zest of 1 lemon
approx 120 ml milk
1 large egg
150g raspberries
12 bun muffin tray lined with 12 paper cases
Preheat oven to 200C/gas mark 6
Melt the butter and set it aside to cool. Stir together, in a largish bowl, the flour, baking powder, bicarb, sugar, salt and zest. In a measuring jug, pour in the lemon juice, then enough milk to come up to the 200ml mark (and it will curdle, but that's just fine), then beat in the egg and melted butter. Pour into the dry ingredients and stir briefly; the batter should scarcely be combined. Fold in the raspberries, spoon this lumpy mixture into the muffin cases and bake for about 25 minutes. When cooked, the tops should spring back to the touch. Leave in the pan for 5 minutes to cool slightly, then sit them on a rack to cool for a further 10-15 minutes.
They sound lovely, think I shall bake some too!
Enjoy!!
