Our school dinners (in the 60's) were pretty standard meat and two veg stuff (sometimes with lumpy mashed potato) which we had to eat or got shouted at by the dinner ladies. But I LOVED the puddings - jam roly poly, chocolate steamed pudding, spotted dick, all with thick custard. Didn't much care for the prunes and custard except that we could eat the prunes and spit out the stones around the edge of the dish and then play "tinker, tailor, soldier, sailor, rich man, poor man, beggar man, thief" (almost made up for the taste of the prunes).
