Once cooled, place the cauliflower into the middle of a clean cotton tea towel or muslin cloth. Gather the edges of the cloth and scrunch/twist the top around. The cauliflower should be sitting in a ball in the cloth and you should keep twisting and squeezing to remove as much liquid as possible.
It’s important to squeeze out as much liquid as possible. The drier the cauliflower, the better the ‘bread’ base will be!
