Does cauliflower soak up liquid? ›

Cauliflower absorbs water like crazy, and the "granules" will become gummy. To keep it fluffy, just let the moisture in the cauliflower do its work.

Does cauliflower absorb marinade? ›

The vegetables actually absorb some of the marinade, helping to season them from the inside out. All you have to do is toss your vegetables in your favorite marinade and let them sit. That's it.

The key to nonmushy cauliflower lies in how you cut it: Break apart the large head into smaller florets. Now take your knife, and starting at the stem end of the floret, slice about halfway down and snap apart.
