Mexican style taco cheese So I know these cheeses are a blend of yellow and white cheddar as well as some Monterey Jack (sometimes pepper jack), but do you know what seasonings are used to make these taco style shredded cheese blends?

I am guessing cumin and chili powder, but if anyone knows for sure that would be great in order to duplicate when recipes call for these shredded blends.
We do a fajita night once a week in my house; so I have tuned the following recipes over the last 10 years or so.  

1/2 tsp of each:
ground cumin
onion powder
salt
chili powder
cornstarch (ONLY if melting cheese)
crushed red peppers (optional for spicy)
garlic powder
oregano leaves
(Heavy cream and butter if melting)


Cheese base is pending my mood; queso fresca, standard white sauce with cheddar or some fancy mexican blend with the standard, colby/cheddar/jack...  

Based on your post i would recommend the colby/cheddar/jack with spices (can we call that the fajita trinity?).
