My mother always cooked with a view to having leftovers hence I am not a lover of such. However, the one I do love and so do my children is Schmarm.
Basically, Schmarm is old pancakes (or even just cooked pancakes) cut into squares and fried in roughly equal parts of butter and sugar until candied. It never works out the same for me because I am never sure of the ingredients ratio but the kids always love it! It is delicious with pureed apricots or other fruit for a healthier meal.
P.S. Schmarm is Mum's name for this. Do you know of any other?
