Forget the terminology it's just confuddling the issue. What your magic addition is Chris is some mix of tomato/onion/garlic/ginger and spices, ground and whole, all fried down nicely together. There's nothing new about that and it's no magic secret. Kris dhillon, for instance, cooks down tinned tomatoes, turmeric and paprika and adds it just like you do. Many other bases add similar fried "mixes" and so do I.
