If using two 6-ounce fish fillets, steam them for 7 to 8 minutes total. It’s possible to use a variety of steamer set ups to make this dish. You can use a shallow pot with a steamer basket and a tight-fitting lid. Or a wok with a small metal steamer rack to elevate the plate a few inches above the water and a domed lid. Or a wok with a large steamer basket and the bamboo lid. With any steamer set up, make sure to use a heatproof plate that fits the steamer basket or rack.
