45 minutes for individual custards (1 hour, 10 minutes for a single custard), plus cooling time
Adapted from Alice Waters' "The Art of Simple Food."
4 egg yolks
3/4 cup cold heavy cream
3/4 cup half-and-half
1/4 cup sugar
1 (2-inch) piece of vanilla bean
2 tablespoons orange liqueur
1. Whisk the egg yolks
in a medium bowl. Pour the heavy cream into another medium bowl. In a small saucepan, combine the half-and-half and sugar. Split the vanilla bean lengthwise, scrape out the seeds into the saucepan and add the bean. Heat the contents over medium heat just until steaming.
2. When the mixture
is warm, remove from the heat and whisk it into the egg yolks. Strain this mixture into the cold cream and mix well. Remove the vanilla bean from the strainer and squeeze all the seeds and liquid from it back into the custard mix, then discard the bean. Mix in the orange liqueur. The mixture can be refrigerated, tightly covered, for up to two days.
3. When ready to bake,
heat the oven to 350 degrees. Pour the mixture into a 2 1/2 -cup custard mold, or into four (one-half-cup) custard cups. Place the mold or cups into a large, deep pan and pour in hot water until it reaches about halfway up the sides. Cover the top of the pan loosely with foil. Bake until the sides of the custards are set but the center is still soft when jiggled, about 50 minutes for the large mold and 25 to 30 minutes for the smaller cups.
4. Remove from the water
bath and let cool. Serve warm, or cool in the refrigerator.
