Mix Dry Ingredients

In a large bowl, combine flour, confectioners' sugar, and salt.

Cut in Butter

Cut in butter until mixture resembles coarse crumbs.

Form Dough and Chill

Stir in egg yolk and cold water, mixing just until dough forms a ball. Wrap and chill for 30 minutes.

Dissolve Sugar

In a saucepan, dissolve sugar in water over low heat. Let cool.

Combine Eggs and Milk

In a large bowl, whisk eggs and evaporated milk. Stir in vanilla and cooled sugar syrup until well combined.

Avoid mixing the custard too vigorously to prevent bubbles.

Strain Custard

Strain the mixture to ensure a smooth custard.

Using a sieve for the custard results in a smooth and silky texture.
