For celiacs, Chinese restaurants are big caution zones, since soy sauce is brewed with wheat. Also, most egg noodles, oyster sauce, hoisin sauce, imitation crab and mock meat substitutes (like mock duck) contain gluten.
Some accommodating Chinese restaurants will prepare entrees without soy sauce, or they may agree to cook with gluten-free soy sauce that you bring in. But cross-contamination is still an issue, so make sure to ask the staff to prepare your food in a clean pan with clean utensils. Dining cards from Triumph Dining, written in Chinese (and other languages) and tailored to specific cuisines, provide an extra measure of safety.
Luckily, some gluten-free soy sauce substitutes are available. San-J wheat-free tamari, certified gluten-free, is the choice in our house. La Choy soy sauce is also gluten-free, though it does contain more processed ingredients.
In our old neighborhood, we were fortunate to find a Chinese restaurant that prepared food without soy sauce for us. We’d routinely order cashew chicken (cooked with a little chicken broth and salt) and corn egg-drop soup.
When we moved, I wanted to make gluten-free corn egg-drop soup that we could enjoy at home. I was surprised at how easy it was. Cream-style corn (which is non-dairy, despite the “cream” in its name) gives the soup body, and whole kernels of corn add to the texture. Silky threads of egg stream through the soup like ribbons. The result: a velvety egg drop soup, enhanced by sweet nuggets of corn, just like in our favorite Chinese restaurant.
