I tried thickening mint tea with cornstarch. I was hoping for something with a more thick mouth-feel. I got the consistency I was looking for, but the cornstarch imparted a slightly mineral/dirty flavor. It certainly didn't ruin the tea, but it wasn't what I was hoping for.
My specific steps were:
- Boil water
- Add cornstarch slurry
- Cook 4-5 minutes more
- Take off heat, add tea bag and sugar (Splenda) then steep.
Will cornstarch always impart this flavor or was it my technique?
Will another common thickener work better (I don't want to have to buy some powder off of Amazon)? Ideally, I would like a thickener that adds no color or flavor, though I'm perfectly happy with one that just adds color.
