• 1 tbsp. orange liqueur, rum or apple juice
Remove stems from the berries, rinse and drain in a colander. Place drained berries on a double layer of paper toweling and dab lightly to dry. Allow the berries to continue air drying while you prepare the custard:
In a medium bowl, stir together 1/4 cup milk, egg yolks and vanilla extract, then beat briskly with a fork until well-blended, and set aside.
Combine flour, cornstarch, sugar, salt and nutmeg in a heavy medium-size saucepan. Stir in the remaining 13/4 cups milk, whisking to combine well. Place the pan over medium high heat and bring the milk mixture to a gentle boil, stirring well. Add the butter and mix again. Cook the milk and flour mixture, stirring constantly, for about 5 minutes or until it is thick and smooth, watching carefully to prevent scorching.
When the milk mixture thickens, remove the pan from heat and stir a few tablespoons of the hot mixture into the beaten egg yolk mixture and whisk until well-blended. Continue whisking in about half of the hot milk to the egg yolks, beating briskly after each addition. Then pour the egg yolk mixture into the saucepan with the rest of the hot milk and beat until well-blended.
