From the Purple Lady in the parish “Team of Neighbourly Help”, which is sort of a branch of Caritas. I think.

3 glasses plain flour

1 glass icing sugar

4 eggs

3/4 packet of margarine or butter [(250g/4) x 3 =  187 1/2g]

Fruit (any kind – raw if raspberries or strawberries or plums, chopped and lightly cooked if apples)

Mix the flour with 4 yolks and 1/2 glass of icing sugar. Layer the dough on your baking tray/tin (lined or greased) and stab it all over with a fork. Bake till golden.

Add a layer of fruit.

Beat the whites and remaining sugar till stiff, add on top of the fruit, and bake till golden.

I don’t have a piccie, so here’re two examples of  Nigella Lawson’s Guinness cake recipe, which also appears to be idiot-proof.  They look a) burnt b) like wet peat hags, but they are neither, and very tasty.
