Ensure your cauliflower is completely dry before beginning. Cut the cauliflower into sizable chunks, including the core, but set aside the leaves for another use or discard them. Place the cauliflower pieces into a food processor and pulse until the texture resembles rice. If necessary, work in batches, being careful not to over-process as it can become mushy. This riced cauliflower can be used in any recipe that specifically calls for it. Simply follow the subsequent instructions in that particular recipe.
