Separate the nuts from the raisins and chop roughly. Then mix in again. Set 75 g of mixture aside. Mix the remaining mixture with 2 tablespoons of flour. Cream fat and sugar. Add the eggs bit by bit.
Add lemon zest and milk. Mix the remaining flour, baking powder and salt and stir into the egg mixture. Finally fold in the floury trail mix. Pour into a greased, breadcrumbed ring cake tin (approx. 2 1/2 litres capacity).
Bake in the preheated oven (electric oven: 175 °C/ gas: level 2) for about 1 hour. Leave to rest in the pan for approx. 15 minutes. Then turn out onto a cake rack and let it cool down completely. For the icing, place the bags in hot water for approx. 10 minutes.
Cut off one corner at a time and pour the liquid glaze evenly over the cake. Sprinkle with the remaining nut-raisin mixture and let it dry. Results in about 20 pieces.
