Hi Stephen where r u from? And how would you describe your pakora sauce?

i'm from elgin (north-east scotland), the pakora sauce that the local birs here do is blended spicy onions with red food colouring (see my post above for pictures, the white tub is from the bir, the big glass bowl is my version)

the alternative one is one i use most commonly (the one with all the tomato sauce and puree), a different style

try this one Gazman, I'm originally from Airdrie and it tastes the exact same as my local kebab shop back there

Half cup of Tomato Ketchup
1/2 teaspoon chili powder
1 teaspoon Mint Sauce
1 teaspoon Vinegar
pinch of Salt
Mix and add water to you get your preferred thickness of sauce.
