GrillGrates are the No. 1 ranked barbecue grill surface in America! This technology has been used to create the Sear’NSizzle Grate for Ninja Foodis. Made in the USA from hard anodised aluminium which will never rust, they have patented raised rails with a flat base plate. It is this design that amplifies the heat for perfect searing whilst drippings are vaporised in the valleys adding flavour and moisture to food.
