I’ve tried this a couple of ways & here’s my conclusions:
It’s much better iced than hot. Also, it’s VERY strong and VERY tart. My first time drinking it, I did 1 cup of hot water to 1 tbsp of Scarlet, and it was overpoweringly tart. No amount of added honey or sugar could stop the tart. It was like drinking a liquid Warhead candy (anyone remember Warheads? No?).
The second time, I tried two teaspoons instead to one cup of boiling water, let steep, and then poured over a handful of ice after adding sugar. Much, much better. When cold, the tartness is staunched a little and you can really taste the fruitiness – more like a Sweet-Tart than a Warhead. I’m getting ready to make up a little pitcher of it this way, in fact.
Oh, and it’s good for a second steep. Haven’t tried third though.
