When I met DH 55 years ago I spent quite a lot of time at his place. (Being away from home) and it took me many years to try some of the dishes. Vareniki wasn’t one. His Mum made soups a lot as the boys wouldn’t eat vegetables I eventually tried Borscht and loved it. She also made another soup with slime green stuff. It looked ghastly. It took me a long time to try it but it was lovely. She wasn’t the best cook, except of Ukrainian dishes.
