why not? Curry rocks, I especially love coconut ones. The only thing that comes to mind is soy sauce could be considered non-primal. But curries tend not to be heavy on that anyway, sub salt for soy sauce if you must.
I never have a concern with the number of ingredients in homemade food. It is boxed foods where I examine the ingredient list and as a rule of thumb avoid long lists because the longer the list the more likely that it contains crap (grains and chemicals).
Why do you say "keep flavorings to a minimum"? Unless I am missing something, I didn't think spices were forbidden.
It's grandma, but you can call me sir.
