to make a basic fritter or egg white batter you'll need self-raising flour egg white olive oil or melted butter salt and warm water and if you're making a sweet batter you'll add some sugar as well begin by placing the flour salt and sugar if you're making a sweet batter into a large bowl then mix the butter or oil with the wool mortar make a will in the center of the flour and at the oil and water mixture and thoroughly mix all the ingredients together till they're combined then beat til you have a smooth batter then allow the batter to stand for about an hour before folding in the whisked egg whites after the batter has been standing for an hour or so fold in the beaten egg whites gently to ensure you don't flatten any of the air bubbles if possible use a flat thin spatula which is less likely to squash the air bubbles you've incorporated during the beating the batter is now ready to use and should be used immediately allowing it to sip will almost definitely cause a loss in volume from the air bubbles dissipating
