Kolwijntjies (south African Queen Cakes)

Stand 24 paper cake cases in 24 bun tins. Set oven to 190 :C / 375 :F / gas 5. Sift flour into a bowl. Cream butter and sugar together until light and fluffy, like whipped cream. Beat in eggs singly, adding a tablespoon of flour with each. Stir in tangerine peel and fruit alternately with milk. Spoon equal amounts into paper cases then bake for 20 minutes until well-risen and golden brown. Remove from oven, leave until lukewarm then cool completely on a wire rack. Store in an airtight container, separately from biscuits, when completely cold. Makes 24
