Diamonds also allow the pan to brown food like stainless steel, creating a fond that can be used for gravy - or easily washed away with warm soapy water. <span class="a-text-bold">Diamonds are naturally nonstick</span> - One of the most valuable properties of diamonds is that they have intrinsic nonstick properties, unlike titanium reinforcement. This gives the coating outstanding nonstick release properties. Gold Medal Winner - International Exhibition of Inventions Best Nonstick Cookware - leading U.S. consumer reporting organization The Rolls-Royce of Nonstick Fry Pans - Wall Street Journal Recommended for vegan and vegetarian cooking - American Vegetarian Association Recommended - Cooking Club of America The rough abrasion movement of sandpaper on the nonstick coating simulates hard wear with metal utensils. The burning of condensed milk with high sugar content simulates cooking and caramelizing of food on the scratched surface. Repeated cycles of abrasion and burning along with washing under cold water tests how deep the scratches can go and how many washing strokes are required to remove food.
