Can anyone suggest the very simple easy recipe for a (European?) dish (not sure what it is called) that my Mother used to prepare...all I can recall is that it was served chilled, and basically contained just sliced cucumbers in vinegar! and it was sweet but not sure if perhaps with a pinch of salt. But I wish to know the instructions, and the ratio of ingredients please. (do not want the recipes that contain oil, onions, or any additional ingredients please). I appreciate any information, thanks!
