I recently moved and couldn't find a thai restaurant nearby. My favorite meal at my old thai place was massaman curry. I used the recipe on the back on the package when I got it, and it was JUST like what I get at the restaurant! Excellent flavor!

When we first bought these we tried to eat one and couldn't.  Looked at the ingredients and found its mostly pig hearts.  Taste is awful.  Our dog however thinks they are great so we cut them up in small pieces and hide them around for him or forage out by smell.  After about a week the contents of the bag start to mold.  Since they are for the dog, we washed them off and then store in the fridge.  Too bad we had hoped these would be good snacks for football parties etc.  Not recommended for people food.
