These are super tastey! I would definitely recommend. The only reason I'm not giving 5 stars is because I wish they were bigger! :D

I was really impressed with this.  There are many flavors, and quite a bit of heat.  With this and your favorite brand of cocunut milk you can make some great Thai curries at home.

This is a fantastic bread mix. I do not use the bread machine, I make it in a bowl, hand made, and have had no problems at all. I do not know why people are having any problems with this. It is terrific. Amazon, please keep this in stock. Please.
