Tart strawberry dessert tea makes me want to add milk. Milk will curdle if hibiscus is in it. My son and i did a small experiment: we cold brewed one and iced one, the milk added to the cold brew did not curdle and the one brewed hot and iced did. There is still the possibility that one had more hibiscus than the other and could effect the curdling.
Tart sweet strawberries and creamy yogurt bits, My son thinks we should get more but I’m not sure because any time I give a choice he never chooses this one.
