For perfect sear marks on your food, utilise the superior heat conductivity of the Cast Iron Searing Grid as an alternative to the Stainless Steel Grid. The two-sided heavy-duty cast iron grid retains the heat enabling a professional quality sear and even cooking on your meat. Flip the grid over for a flatter searing surface for meat, fish or seafood. A must have for a meat lover! Buy two half moons for a full diameter.
