What is a good spicy potato wedges seasoning? I've taken a liking to the simple potato wedge as an alternate to mash potato when preparing meat and three vege. However, I'm trying to get a recipe that consistently deliveries tasty wedges.

My current method is:


Wash potatoes
Chop potatoes
place in plastic bag 
Add a little oil and spice mix*
Shake 
Bake


* The spice mix is the part I've been having problems with.

I was using:


1 part salt
2 parts pepper
3 parts paprika


But this wasn't giving consistent results.

I've stuck with Nandos Peri-peri seasoning for a while as a safeguard, but I'd like to go back to my own spice mix.

I'm looking for spicy Mexican flavours, but using only spices/herbs, and not salts or flavour enhancers, apart from sea salt (not garlic salt or onion salt).

Any suggestions?
Add cumin, chili powder and garlic powder to your salt and pepper. You might like a bit of curry powder or turmeric too, but I don't know if you'd call that a Mexican flavor.
