Olive and Grape Cauliflower Leaf I recently rustled. I had been experimenting with grape molasses which are an addition to my repertoire. Much like beet greens, I love cauliflower leaves that form the usually discarded part of a cauliflower head. The outer leaves of a cauliflower are delightful and edible too. Olive and Grape Cauliflower Leaf are a thumbs up from me.
