Pick cauliflower when heads are full, but before curds begin to….

Separate. Cut through stem under head, leaving a few "wrapper" leaves for protection. Curds bruise easily, so handle with care. Before eating or storing cauliflower, soak it in lightly salted water (1-2 tablespoons salt per gallon) for 30 minutes to drive out any unnoticed cabbageworms that may be hiding in heads.
