Hmmm, you could put the cooked pieces in a colander (draining bowl) and press with the bottom of another bowl that fits close to the size of the colander. This could squeeze out some water, and works for cauliflower 'potatoes' too. OR, you could put the cubes on a clean towel and fold towel over and press a few times. I've done both of these and I actually prefer the towel, but that's me

good luck to you!
