I pretty much do the same anymore. Only teas I use cream and sweetener is Earl Grey and other similar blacks. Otherwise I largely go without.
Mint and vanilla sounds nice. I might have to try that.
Was told my painting would be ready tomorrow, so while Im in the next town over picking it up, I'm going to stop by the tea shop for some dried herbs. I've been enjoying matcha mixed with lavender recently. They sell lavender, and quite a few other herbs.
