Preparation

• Position a rack in the center of the oven and heat the oven to 300°F. Fill a teakettle with water and bring to a boil. Put four 5- or 6-oz. ramekins (about 3 inches in diameter and 1-3/4 inches deep) in a baking dish that’s at least as deep as the ramekins.

Mix the custard base:

• Pour the cream into a small saucepan. If using a vanilla bean, cut it in half lengthwise with the tip of a paring knife and, with the back of the blade, scrape out the sticky, black seeds. Add the seeds and scraped pod halves to the cream. Whisk briefly to disperse the seeds. (Don’t over-whisk or you’ll whip air into the cream.)
• Bring the cream just to a simmer over medium heat. Remove the pan from the heat, cover, and let sit for about 10 minutes.
• Meanwhile, in a medium mixing bowl lightly whisk the egg yolks, 1/4 cup of the sugar, and a pinch of salt just to combine. Set aside.
• With an instant-read or a candy thermometer, check the temperature of the cream; it should be no higher than 165°F. (If it is, let cool to 165°F before proceeding.)
• 将约1/2杯奶油轻轻搅拌到蛋黄混合物中，搅拌约30秒；这使蛋黄倾斜。然后轻轻搅拌剩余的奶油，搅拌约15秒钟以混合。用轻手 - 您不想制作泡沫的混合物，否则烤蛋ust的表面将具有泡沫状的表面。如果使用香草提取物，请立即搅拌。
• Set a fine sieve over a large Pyrex measuring cup or a heatproof bowl with a spout. Pour the custard base through the sieve to strain out any solids.

Bake the custards:

• 将蛋ust基地均匀地划分为烤盘中的四个小动物。每个小模子中应该有一英寸的蛋ust。它不应该一直到边缘。慢慢将热水从柚木植物中倒入烤盘中（在小模子中不要水），直到水沿着拉米金斯（Ramekins）的侧面约为三分之二。
• Carefully transfer the baking pan to the center of the oven, taking care not to slosh hot water onto yourself or into the ramekins. Lay a sheet of aluminum foil over the pan. Bake the custards until the edges are set about 1/3 inch in from the sides of the ramekins and the center is slightly jiggly (like Jell-O), 40 to 55 minutes. To test for doneness, reach into the oven with tongs and give one of the ramekins a gentle shake or nudge. If the custard responds with a wavelike motion rather than a slight jiggle, it’s not firm enough; bake for another 5 minutes and check again. (If you’re not sure about the doneness, stick an instant-read thermometer into the center of a custard—don’t worry about making a hole; you’ll cover it with sugar later—it should register 150° to 155°F.) The custards should not brown or rise.
• Carefully remove the baking pan from the oven and take the ramekins out of the water bath using rubber-band-wrapped tongs or a slotted spatula. Let the ramekins cool on a rack at room temperature for 30 minutes and then transfer, uncovered, to the refrigerator to cool completely. Once the custards are refrigerator-cold, wrap each ramekin with plastic wrap. Refrigerate for at least 3 hours or up to 2 days before proceeding.

Caramelize the topping:

• Just before serving, remove the ramekins from the fridge and set them on a work surface. Working with one custard at a time, sprinkle 1/2 to 1 tsp. of the remaining sugar over each one—the more sugar, the thicker the crust. You may need to tilt and tap the ramekin to even out the layer of sugar. Wipe any sugar off the rim of the ramekin. Hold the torch flame 2 to 3 inches from the top of the custard and slowly glide it back and forth over the surface until the sugar melts and turns a deep golden brown. Allow the sugar to cool and harden for a few minutes, and then serve immediately, before the sugar softens and gets sticky.

For variations, just infuse the cream with flavorings

Orange: Omit the vanilla bean and after the cream comes to a simmer, remove from the heat and immediately add 1 Tbs. Grand Marnier or Triple Sec, 2 tsp. (firmly packed) finely grated orange zest, and 1/2 tsp. vanilla extract. Cover and let sit for 10 minutes.

Ginger: Omit the vanilla bean (or extract), and instead add 1/2 Tbs. (firmly packed) finely grated fresh ginger to the cold cream before bringing it to a simmer.

Café au lait: Omit the vanilla bean (or extract), and right after the cream comes to a simmer, remove it from the heat and whisk in 1-1/2 tsp. Medaglia d’Oro instant espresso powder (available fromGourmetsleuth.com) until dissolved. Cover and let sit for 10 minutes.

Earl Grey tea: Omit the vanilla bean (or extract), and after the cream comes to a simmer, remove from the heat and immediately add 5 tea bags (you may have to prod the bags with a spoon to submerge them). Cover and let sit for 10 minutes.
