I just mix plain flour with a pinch of salt, a pinch of sugar, half a teaspoon of sodium bicarb, half a teaspoon of tartaric acid, and sufficient cold water to enable it to be beaten to a single cream consistency. Then I refrigerate it for at least twenty minutes.
Just before use, I mix in about half a teaspoon of malt vinegar.
The rest is a good thing, allowing the flour to fully hydrate, making the batter smoother.
Part of the idea of using beer, and the intention behind sparkling water or bicarb + tartaric + vinegar, is to generate some CO2 bubbles when the batter is heated.
I just wonder whether leaving the addition of the bicarb etc until after the batter has been rested, might better postpone the gassing until the batter is actually being used.
An alternative (or addition) to adding gassy ingredients, as advocated by Sophie Grigson (to name but one) is to separate the eggs, mixing the yolk in with the flour etc in the mix for resting. However the white of egg is beaten stiff, and folded in, full of air bubbles, to the rested batter immediately before using.
But I think that's closer to Michelin practice than to the typical chippie!
