Can you name these leaves?
I picked these leaves at the market yesterday for their freshness and pretty shape. The vendor didn't help me much with a name in any language I knew. All he said was they tasted sour, which they did as I promptly tasted and tested. I think they'd do well in a salad with other veggies, but my husband thinks they should be ground into a lovely chutney. Can you tell me what these leaves are and how they are used in cooking? This is not a guessing game and all information and suggestions are welcome.
