Do you love cooking with a wok on your gas stove? This simple but genius tool can make a big difference. It's an enamel-coated steel ring (also called a fire hood or windshield) that sits on your burner. What does it do? It wraps around the bottom of your wok, concentrating the flames and heat right where you need it, instead of letting it spread out and waste energy. This makes your stove more efficient, helps water boil faster, and can even save you some on your gas bill. It's also windproof, so drafts won't mess with your flame. It's made of durable enameled material, measures about 25.2cm x 25.2cm x 5cm (roughly 10\ x 10\ x 2\), and comes in black. Easy to place and remove for cleaning. Great for home cooks or even small restaurants. Get better wok hei (that coveted 'breath of the wok' flavor) and cook like a pro!
