You may have noticed that we refer to the pastry in our sugar plum fairy puffs as choux pastry. u003cbr/u003eu003cbr/u003eChoux pastry is different from puff pastry and shortcrust pastry because its main ingredients are flour and water, and it’s made very light and fluffy by the gradual addition of eggs into the batter. u003cbr/u003eu003cbr/u003eChoux pastry should be hollow in the middle (allowing you to fill the pastry with creams and jams of your choice) and moist on the outside. u003cbr/u003e
