    The common element is carbonation. If you don't have beer (or don't want to use it) you can substitute soda water.

    It actually says "or". Also baking soda can be used if no beer nor soda water are around.

1 Answer 1


The carbonation in soda water (or beer...or the use of a whipping siphon) is added so that the batter becomes more "airy", leading to a lighter and crispier final result after frying.
