Thanks, people, for the tip1 on adding our own blends to the “Custom” brand. It’s not a perfect method, but given the state of things, it’ll do.
Can I just tell you guys how happy I am right now? This blend is so yummy! The Twinings perfectly fills the orangey void in Numi’s tea. From the fragrance to the sips to, well, even the aftertaste(!), the sum here is far, far, FAR better than its parts. I’m so glad I decided to try this little experiment; now I won’t have to bore you by repeatedly whining about the weak bagged teas I have to get through. :D
A quick note about water temperature: the Numi box (white tea, remember) says to boil the water, which doesn’t really make sense to me. The Twinings box says the same for the honeybush, which does make sense to me, so I split the difference and steeped for 10 minutes. It seems to have worked well.
