Welcome to the board! Can you give a brand name for that sauce? Looks like a Caribbean-type, yellow-green style.
You'll need to learn to make the purees, which would be a good thing to know anyway. I suppose you'll need that xanthan gum to keep it from separating. Note it's the last ingredient so you shouldn't need much.
One big variable is the chile powder; it could be anything from mild to killer hot. That would be where you can choose how hot you want it to be.
It will probably take a few tries to get what you're hoping for, but you might be able to do it.
