Step 1

Whisk the whole milk and heavy cream together. Set aside. Whisk the egg yolks and cornstarch together. Set that aside too. Have both ready to go in step 3.

Step 2

Whisk the brown sugar, water, and salt together in a medium heavy duty saucepan over medium heat. Without stirring, allow to cook and bubble until darker brown, about 5-6 minutes. It should begin to smell caramelized at that point. If desired, you can take the temperature with a candy thermometer to be certain it is ready. Look for around 240°F (116°C).

Step 3

Slowly and carefully whisk in the heavy cream/milk. It will sizzle and may splatter, so pour in slowly. Cook on medium heat until mixture begins to boil. Once boiling, remove about 1/2 cup of the mixture and, in a slow and steady stream, whisk into the egg yolks. Keep those egg yolks moving so they don’t scramble. In a slow and steady stream, pour and whisk the egg yolk mixture into the pot.

Step 4

Turn the heat down to low. The pudding will immediately begin to bubble and thicken. Whisk and cook for 1 minute. Remove from heat and stir in the butter until completely smooth, then add the vanilla and bourbon.

Step 5

Cool for 5 minutes, then pour into serving glasses or bowls. Cover tightly with plastic wrap directly on the surface of the pudding (to prevent a skin from forming) and refrigerate for 4-6 hours or overnight until chilled and thickened.

Step 6

Serve with optional toppings. Cover and store leftovers in the refrigerator for up to 4 days.
