Basic Choux Pastry Workshop
Processing steps (paste cooking):
- Bring the milk, water, sugar, salt and butter to a boil, stir to combine.
- Remove from heat source, add the flour and continue stirring.
- Heat the mix again while stirring till the mixture becomes a cohesive mass and clears the side of the pot.
- Transfer the mix to a mixer with a paddle attachment. Mix on low speed until the mix reaches a temperature of around 43–60°C then add ¾ of the eggs gradually until fully incorporated.
- Add the remainder of the eggs until the desired consistency (viscosity) is reached. The paste should be smooth and moist but firm enough to hold its shape. Alternately, hot milk may be added to the mix to adjust its consistency.Processing steps (paste baking):
- Pipe or deposit the mix to achieve the desired shapes.
- Bake the choux at 176°C (350°F) for 10 minutes in a convection oven with the vent closed and then at 163°C (325°F) for 15–20 minutes with the vent open.
- The baked product must have a well-browned exterior with a dry center.
Choux pastry, also known as pȃte à choux, is a twice-cooked hollow French pastry. It’s made from choux paste and is typically eaten cold. A sweet version is normally filled with cream and garnished while a savory version can be filled with shellfish, vegetables, cream cheese and foie gras to be served as hors d’oeuvres.
For a successful production of choux pastry, the following options can be used:2
- Generally, a combination of water and milk is used in the recipe but all water or all milk may also be used. Higher milk levels improve the pastry tenderness and color while high water allow for higher baking temperatures.
- Margarine or shortening may be substituted for butter if required.
- Pastry flour is preferred due to its milder protein content which prevents cracking and distortion of the pastry during baking. Bread flour may also be used, but this may require higher hydration of the flour and may reduce expansion of the baked product.
- A small quantity of sugar that may be added to the recipe to provide the baked product with desirable color and flavor (along with the salt).
- Excessive boiling of the liquids should be avoided due to possible deleterious effects on flour hydration.
- Overcooking the mixture after adding the flour may cause denaturation of the proteins, resulting in incomplete absorption of the eggs and the formation of a non-homogeneous mix.
- Since the pastry relies completely on steam for leavening, it is important to ensure there is a sufficient amount of water (from water, milk and eggs) in the paste.
- Both unbaked and baked choux paste can be stored in the freezer. The unbaked mix can be thawed and baked as normal when required.
- It is important to keep in mind that all baked choux paste products have a short shelf-life due to issues with texture deterioration.
