This 4-Piece Accessory Kit makes the Roma Food Strainer & Sauce Maker the most versatile tool in any kitchen. Make your own salsa, strain the seeds from strawberries to make your own jellies, or create puree for pumpkin pie from scratch. All three accessory screens are made of the same high grade stainless steel as the standard Roma screen. The Grape Spiral allows the Roma to strain grapes while separating the seeds and skins for homemade juices, great for the home wine maker. Screens also sold separately.
