This is a very traditional Polish dessert. This is a recipe my grandmother got when they lived in Poland for 10 years. We usually have this at Christmas and other special occasions. It’s a fairly rich, potent dessert so if children will be eating this you can leave out the alcohol and use 1 tsp each of rum and almond extracts to give the flavor. It is similar to a tiramisu but we use stale or toasted raisin bread or egg loaf slices. You could probably substitute lady fingers.
