This is a variety we've never encountered in supermarkets but appeared abundantly among our upland organic farmers' gardens. Takes about sixty days to grow with multiple harvests before maturity makes it bitter or tough (like people you know?) But the farmers like it because it grows so well especially at this time of year. The care for us as market facilitators is to:
Remind farmers not to pick beyond maturity (when it flowers).
Promote a cyclical purchase and production so gardens don't turn into monocultures.
This variety travels pretty well and it can keep in your refrigerator for two weeks when dry (with towel absorption). As for food prep, you can have it raw in a salad or blitzed in a smoothie. Here's a good source on the nutritional benefits either way.
