4tablespoonsunsalted buttercold and cut into 4 pieces
5large egg yolks
3tablespoonscornstarch
2cupshalf-and-half
½cupgranulated sugardivided
¼teaspoonnutmeg
1pinchtable salt
1½teaspoonsvanilla extract
Instructions
Place a fine-mesh strainer over a medium sized bowl with a wire whisk. Set this aside.
Set aside the cut, cold butter.
4 tablespoons unsalted butter
Whisk the egg yolks in a medium bowl then add 2 tablespoons of sugar and whisk until it has started to dissolve and mixture is creamy, around 15 seconds.
5 large egg yolks
Whisk in the cornstarch until combined and the mixture turns a thick, pale yellow, about 30 seconds.
3 tablespoons cornstarch
Bring to a simmer the half-and-half, 6 tablespoons sugar, nutmeg and salt in a medium saucepan over medium heat, stirring occasionally to dissolve sugar.
2 cups half-and-half, ¼ teaspoon nutmeg, 1 pinch table salt
When the half-and-half mixture has reached a full simmer, gradually whisk it into the egg mixture, which will temper it. Return this combined mixture to the saucepan, making sure to scrape the bowl with a rubber spatula to transfer the entire amount.
Return the custard mixture to a simmer over medium heat, whisking constantly, until a few bubbles burst on the surface and the mixture thickens and becomes glossy. This can take as little as 30 seconds or considerably longer. The important thing is not the actual time but rather that you continue to cook until the mixture thickens until it become the consistency of pudding. If it's not, keep whisking constantly until it thickens. The refrigeration step will help set the pastry cream, but if it's not thick at this point, it won't thicken enough upon chilling. If you're wondering if it has thickened, it probably hasn't because it's pretty obvious and happens quickly.
Remove the pastry cream from the heat and whisk in the butter and vanilla.
1½ teaspoons vanilla extract
Transfer the pastry cream to a fine mesh sieve set over a medium bowl. Whisk it to force it through and remove any lumps or egg clumps.
Press plastic wrap directly on the surface to avoid getting a "skin" on top.
Refrigerate the pastry cream until cold and set, a minimum of 3 hours and maximum of 48 hours.
