John, that's what I was calling refrigerator cake - and there's one in the fridge at the moment.

I've sort of gone with the fruity idea, but will add the yoghurt instead of the custard. I've made strawberry jelly (jello) which took an age to dissolve, poured it over them in a glass bowl, and I'm on my way to soggy biscuit trifle. I didn't put the fruit into it, for keeping purposes, but will add on serving.

I'm sure the situation will arise again, so any other ideas will be gratefully received.
