Similar to radishes but starchier and sweeter, turnips will hold up in your fridge for a pretty long time. 

Amelia Tarpey, Program and Publicity Manger for GrowNYC Greenmarkets, says you can shave them into a salad, make a purée, or turn them into Lebanese pickled turnips to go on the side of a lamb roast. 

Right now at Greenmarkets, you can expect turnips to go for around $4 a pound.
