We were in an Aldi supermarket today when we came across bags of German ginger biscuits, including the spiced ginger "magen brot". We had to buy a bag!
While in Frankfurt in 2004 we visited the Friday night street market/beer garden and stopped by the sweet stall pictured on the right. Convinced by the stall owner to try some magen brot we liked it enough to buy a bag. Initially we thought that he had given us too much, but then I found myself compulsively eating square after square of the ginger bread. My only regrets were not buying more and that it generates a fair amount of internal gas!
