Pancake mix in particular benefits from the large scales at which the pre-mixed stuff is made. Measuring out those smaller proportions of dry powders precisely and accurately is much more difficult at home even if you opt for using a scale instead of measuring cups. Just read the ingredients list to avoid the brands that may include the extra binders and other ingredients you want to avoid.
I live in a hot climate so my favorite teas are iced.
Iced oolong sweetened only with some lychee chunks is the only thing close to boba I can stomach. I also like a good iced jasmine green tea. Or just a strong green tea hot or iced.
