1 Mars Bar
1 cup plain flour
1/2 cup corn flour
A pinch of bicarbonate of soda
Milk or beer
Oil for deep frying
Chill the chocolate bar by keeping it in the fridge, but don't freeze it.
Mix the flours and bicarbonate of soda (baking soda) together.
Add milk (traditional) or beer (which gives a lighter result) until you get a batter with the consistency of thin cream.
Heat the oil until a small piece of bread will brown in a few seconds, but don't allow to smoke.
Remove wrapper from chilled chocolate bar. Coat completely in batter. Carefully lower into hot oil and fry until golden brown. Serve with ice cream.
(Of course, if you want to be sophisticated, you can cut the bar into bite-sized pieces before coating in batter.)
