As an update to this thread just took delivery of this evenings Curry and it was the Boss of the T/A doing the delivery,I asked if they really deep fried their Bhaji's in Butter ? and chriswg was right

they deep fry Bhaji's in Veg Ghee, I'm definitely going to try this but not sure how long Veg Ghee would last in a Deep Fat fryer out of the Fridge

Just read up about Veg Ghee and Trans Fats

Don't think I'll bother !
