Set up your steamer. If you have built in oven steamer or fish oven, prepare per factory recommendations. However, if you don't have a steamer, don't worry as long as you have a wok or deep pan with a tight fitting lid then you can create a modified steamer with common things around the house. There are 4 options that work very well for us..1) Metal wok steamer plate inserted in a wok or deep pan with a plate on top. 2) Two chopsticks criss crossed in a wok or deep pan with a plate on top. 3) Ramekin or small dipping dish upside down, then your flat plate on top of that and lid on top of that. Apple Corers are another great option as they are just slightly elevated. 4) Bamboo steamer on top of a pot or in a wok.Place enough water at the bottom of your pan so that the water level is at least 2 inches away from the steamer basket, plate, etc. Turn on your burner and bring your steamer to a boil. Watch the video below and you watch how this works in action. (If you are planning to serve rice with your meal, start cooking your rice now, if diabetic or watching your carbs replace the rice with more assorted veggies, mushrooms or cauliflower rice)
Place peeled and sliced diakon slices (or other vegetables like carrot slices or lettuce) on your steaming plate to prevent your fish from sticking to the plate or steamer basket.
Place cod fish fillets (or any mild white fish of preference like mahi mahi, tilapia, haddock, etc.) on top on the diakon radishes (or other vegetables) on your steaming plate (bamboo basket). If you prefer to steam a whole fish, see recipe notes for details.
Place julienne sliced ginger on top of fish fillets (if using whole fish stuff the cavity of the fish with ginger slices). Just as a quick note you will needing more ginger julienne slices for the Asian sauce.
Arrange bok choy or other green vegetables of choice around fish. Once the steamer water comes to a boil, put your fish with bok choy plate into the steamer. Depending on the size of your fish, you will need to stream your fish between4 or up to 8-10 minutes. Larger or thicker fish fillets or whole fish will take longer to cook than thinner fillets. Our cod cooked in 4 minutes. Your fish should flake easily with a fork and no longer be translucent. The quick cooking green veggies should be aldente.
In the meantime, make your Asian sauce. In a small pan, add oil, ginger, garlic, half of the green onions, dashi broth, mirin, sugar or sugar alternative, soy or tamari sauce and white pepper to taste. Adjust seasoning to taste. Just before removing the sauce from the pan add the rest of the green onions and give it a quick stir.
Remove fish and bok choy from steamer and drain well. Drizzle Asian sauce on top and sesame oil. Garnish with Cilantro (coriander)and enjoy! Serve on its own for a low carb dinner or with rice for a delicious full meal.
