How to Make a Kansui Powder Substitute
Using Only Baking Powder
Sometimes a recipe calls for an alkaline ingredient. This is the case with ramen noodle dough. It's the alkalinity of the dough that contributes that characteristic ramen snap, as well as it's egg-like color and flavor. In Japan, kansui powder is a somewhat common alkaline ingredient. But if it's not available in your area, you can get a good substitute by heating baking soda.
