Earl at market usually removes the carrot tops for customers, but he told me that the tops are, actually, edible. Chopped up in salad. Or added to whatever other greens you are cooking. Since Earl told me that, I've done both those things, but recently I bagged some carrot tops and froze them. Then when I hauled out the stock pot to make chicken stock, I added the carrot tops instead of celery. Feeling very 1930ish indeed and wondering what else is edible that I usually compost.
