This doesn't help you with your current abundance, but I highly recommend Japanese turnips to all! Varieties that I grow for market and love are Hakurei & Tokyo Cross (white skin, white flesh) and Tsugaru Scarlet (red/pink skin, white skin with white flesh streaked with pink). Best harvested golf ball size, the texture raw is like a crunchy apple (scarlet are slightly more dense), and the flavor is like a sweet, mild radish, so they are great in salad. They also go well in mixed root veggies, and make amazing pureed turnip soup. For the spring crop I love them lightly sauteed in butter with sugar snap peas.
