I'm trying to create steamed cupcake and one of the ingredients needed to make it "grow" is emulsifier. I know it's not commonly sold, but I heard you can find it in Asian stores. I have tried Marche Hawai and G market in china town, but I don't know where else I can find it. So can anyone help me find a store?
I also heard Xantham gum as a subtitute, but I'm worried it won't create the "growing" effect I need.
