300 gm unsalted butter
500 gm plain flour
150 gm sugar
1 dash salt
1 single egg yolk
1 single egg
Put the butter, cut into pieces, with the flour, sugar and salt, into a mixer. Work it until the mixture resembles coarse semolina.
Add the egg yolk and the whole egg and do not work the machine for a moment longer than necessary (VERY IMPORTANT) to amalgamate the eggs with the flour mixture. Form it into a ball and leave it to rest in the refrigerator for several hours before using it.
(The pastry will keep very well in the refrigerator for a few days, wrapped in transparent film)
