The type of garlic ginger paste that SD refers to is indeed the Ashoka recipe but the Ashoka method is a particular take o cooking curries that matches the g/g paste with a bunjarra (onion paste) and also the Ashoka base. I see no reason as to why you can't make g/g paste with flavoured oil. I don't, but that's only because I don't use flavoured oil when making a curry.
