Calphalon Unison Nonstick cookware gives you professional results with nonstick convenience. The Grill Pan & Press cooks both sides of your food at once to seal in flavor, drain unwanted fat and hold in heat for delicious results. To use, warm the cast iron press on a separate burner while the pan preheats. Then use the press to weigh down chicken or steak for even searing and browning. The Sear Nonstick surface is ideal for chicken, steak, burgers, Italian-style panini and traditional Cuban sandwiches.
