Source: Thomas Keller’s Bouchon I just purchased a set of these mini Weck jars and love them especially for these pots de crèmes, which are traditionally baked in lidded vessels. The original recipe calls for using eight 5- or 6-oz pot de crème molds. Of course, if you have 4- or 6-oz ramekins, those will work, too. The mini Weck jars are much smaller (2.7-oz), which is kind of nice for such a rich dessert, but again, use what you have. Also, apparently making a chocolate variation is simple: Finely chop 6 ounces semisweet chocolate and place in a metal bowl. Then, in step 2, when you strain the mixture, strain it into a saucepan instead of a measuring cup. Heat the custard until it is warm, then pour it over the chocolate, let it sit to melt, then whisk it together until it has combined. Proceed with recipe. Note: I have not tried this variation yet.
- 2½ cups heavy cream
- ⅔ cup milk
- ½ cup plus 1 tablespoon sugar
- 1 vanilla bean
- 6 egg yolks
- Combine cream, milk, and 5 tablespoons of the sugar. Split the vanilla bean in half lengthwise, scrape the vanilla seeds into the cream, and drop in the empty pod as well. Heat mixture until it’s hot to touch and sugar has dissolved, then remove pan from heat, cover, and let it steep for an hour (if possible).
- Whisk the egg yolks and remaining ¼ cup sugar together. Re-heat the cream mixture till it’s warm to the touch — not hot. Slowly whisk a small amount of the cream mixture into the yolks to temper them. Continue adding the warm cream until all of it has been added. Strain the entire mixture through a fine mesh strainer into a pitcher or large measuring cup. At this point, the mixture can be refrigerated for several days.
- Place rack in center of oven and preheat oven to 300º. Bring a teapot filled with water to a boil. Place pot de creme molds (see notes above) in a large deep baking pan (a 9×13-inch pan should fit all of the molds) lined with parchment paper (or not). Place the baking pan on a sheet pan: This will provide double the insulation so the custards can cook evenly and slowly. Gently stir the custard, then fill each vessel with it. Cover each mold with a lid or wrap each ramekin in plastic wrap (the horror! I did this once, and it worked, so if you’re not afraid of plastic wrap, go for it).
- Place pan in oven leaving a few inches sticking out to allow you to pour in the hot water from the teapot: pour in water to come in halfway to two-thirds up the sides of the molds. Place in the oven and bake for 30 to 55 minutes — the cooking time will vary depending on the size of the vessel and if the custard was refrigerated or not. To test, reach into the oven and using a tea towel to protect your hand, gently shake one of the molds — the custard should be set, but will still jiggle slightly, like gelatin. Remove the molds from the hot water and place on a cooling rack.
- Let cool, then refrigerate for at least 8 hours before serving.
