I've been intrigued by this curry flavored taco thing. My mom brought me a few packets of taco seasoning from the states and I happen to have a UK OEP one too. These are the ingredients:
OEP
Dextrose, green pepper powder, salt, flavourings, black pepper, cumin, yeast extract, onion powder, garlic powder, citric acid, paprika extract.
Lawrys
Paprika, cumin, oregano, chili peppers, onion, salt, lactose sugar, garlic powder, wheat flour, cocoa powder, citric acid, natural flavor
