Buying and Storing Romanesco
When selecting Romanesco, look for heads that are bright in color and have their leaves still attached. The stems should be firm and show no signs of wilting. When you pick up a head, it should be heavy for its size. Once you bring it home, store your fresh Romanesco unwashed in a resealable plastic bag in the fridge for up to 1 week.
