So many cultures have a refreshing yoghurty dip: raitha for the Indians, tzatziki for the Greeks. Call it what you like, I love this stuff and can eat it for breakfast, in bed, lunch or dinner.As for the mint, you could use an Indian trick: mint sauce in a jar! Or try other fresh herbs such as coriander, dill, parsley, tarragon (very Georgian).Another option is to use radishes instead of cucumber, which gives it an attractive pink hue.
