The wheat free brownie mix is not to my liking.  I won't be reordering. I'd rather not eat chocolate than to eat these brownies.

Ex Input:
I was looking forward to this tea, but unfortunately the mint overpowers the hibiscus and essentially makes this just another kind of mint tea.  I prefer the hibiscus tart be the star of the show in a hibiscus-based tea (aka "herbal infusion") and in my opinion, mint and "tropical" don't mix and now know going forward to pay more attention to the ingredients.  Still worth 3 stars because it can be a refreshing tea on a hot day, but just not a great tropical/hibiscus tea.

I recently went gluten free and this is one of my favorite mixes.  I used it for biscuits and pancakes and it's very good.  You can also use it for pizza dough and to make fried chicken - it's about average for that.
