Low-carbohydrate potato products include potato and cauliflower. Preferably, they are mixed together dry with a suitable water-dispersible or water-soluble binder. The dry mix can be prepared by mixing dried potato and dried cauliflower. A preferred form of the mix can be prepared for serving by mixing with water to provide a suitable consistency for final preparation, e.g., by simply heating or frying or baking. Potato products, especially those prepared from the dry mix and the above process are also described. Products that do not require shelf-stable storage do not require dry ingredients for their preparation and can be made from the indicated ingredients without drying by simply mixing the ingredients, e.g., potatoes and cauliflower, in their natural or cooked state.
