I recommend getting the culinary grade matcha from Mizuba. I have tried several powders on the market, and I always need to get a ceremonial grade for my lattes (which is what I would normally recommend unless you are using this specific brand.) It can get quite expensive but with Mizuba’s culinary grade, the quality is perfection, and you can make 50-75 servings with one bag!
The collagen peptides are optional, but they do help with the overall frothiness and end result in texture of the matcha. If you are vegan or do not have access to them, you may omit.
Be sure to use a liquid like MCT oil as your fat source if making an iced matcha. Otherwise, an ingredient like coconut butter will result in a clumpy end result that’s not very palatable.
