Press out quickly into a large rectangular cake, wrap in plastic film and refrigerate for at least 1 hour before using.
Remarks
The proportions for this dough are very easy to remember: 100 g flour to 1 egg and 4 g fine salt.
This dough tends to turn brown rapidly, so if you are making it for use the next day, add 1 tablespoonful of white vinegar to the ingredients before kneading to slow down the discolouration.
