Zubereitung

1. 1

   In a bowl, whisk together the egg yolks, sugar, vanilla, and salt.

2. 2

   Pour the half-and-half and cream into the top of a double boiler** and heat over hot water until hot, but not boiling. Stir with a wooden spoon, scraping the bottom of the pan to prevent sticking.NOTE: I carefully heated the milk and cream in my microwave, being careful not to let it boil. Personally, this is easier for me.Slowly pour some of the hot cream into the eggs, to temper it. Slowly add the rest of the hot cream, whisking constantly until smooth.Return to the double boiler** and cook over medium-low until thick and bubbling around the edges.NOTE: I used direct heat, being very careful to stir constantly and to keep the temperature on medium-low. It took about 15 minutes for the custard to thicken, so be patient!The custard will coat a wooden spoon. You can also coat a regular spoon, run your finger through it. If the line remains separate, it's ready!Strain the custard through a fine-mesh sieve into a metal bowl (don't skip this step). Cover and chill for at least 4 hours or overnight.HOMEMADE LEMON CURD (Optional):In a 2 quart saucepan, combine lemon juice, lemon zest, sugar, eggs, and butter.Cook over medium-low heat until thick enough to hold marks from whisk, and first bubble appears on surface, about 6 minutes.
