Found on islandteashop.com while I was searching for different ways to use the matcha (green tea powder) I just ordered for myself. The authors of the site suggest brushing it on pork loin or salmon before baking, using it as a dipping sauce for dumplings, or trying it as a salad dressing. I bet it would be great in other things, too. Easy and different, why not give it a try? :) Serving size depends on preference and what you decide to do with it; you'll want more for a dipping sauce, probably, than you would for a brushed-on glaze.
