I think I have issues with cornflower petals. Any time I make a tea with them, it has a bitter, astringent taste. Everyone talks about tea made with them being so creamy. I’ve tried this tea at 2, 3 and 4 minutes and still get that flavor. Am I missing something? Do you have to add sweetener and milk for the creaminess to come out? That doesn’t seem right. And when I do, I don’t get any of the caramel or hazelnut taste. I really want to like this tea. Help!
