Ingredients:
- 6 Tbsp unsalted butter
- 3/4 cup (165 g) dark brown sugar, packed
- 1/2 tsp fine sea salt
- 1 1/4 cups whole milk (divided)
- 1/2 cup heavy cream
- 3 large egg yolks
- 3 Tbsp cornstarch (Maizena)
- 1 tsp vanilla extract
Instructions:
- Prepare the Slurry: In a medium bowl, whisk together the egg yolks, cornstarch, and 1/4 cup (60 ml) of the whole milk until completely smooth and pale yellow. Set aside.
- Create the Butterscotch Base: Melt the butter in a medium heavy-bottomed saucepan over medium heat. Continue cooking until the butter foams, subsides, and the milk solids turn a nutty, golden-brown (creating brown butter).
- Caramelize the Sugar: Add the dark brown sugar and salt to the brown butter. Stir constantly for 2–3 minutes until the sugar melts and the mixture smells deeply caramelized, dark but not burnt.
- Incorporate Dairy: Slowly and carefully whisk in the remaining 1 cup whole milk and the heavy cream. The mixture may seize initially; continue to stir over medium heat until all the hardened sugar is fully dissolved back into the liquid, forming a smooth, warm base. Bring the mixture to a low simmer.
- Temper the Yolks: Remove the saucepan from the heat. Slowly ladle about 1/2 cup of the hot milk mixture into the prepared egg yolk slurry while vigorously whisking the slurry.
- Thicken the Pudding: Pour the tempered egg mixture back into the saucepan with the remaining hot liquid. Return the pan to medium-low heat. Cook, stirring constantly with a spatula, until the pudding thickly coats the back of a spoon and starts to gently bubble (about 3–5 minutes). The pudding is ready when it makes a slow 'plop' sound as it falls from the whisk.
- Finish and Chill: Remove from heat and stir in the vanilla extract. Immediately pour the entire pudding mixture through a fine-mesh sieve into a clean bowl or individual serving dishes to catch any lumps.
- Prevent Skin Formation: Press a piece of plastic wrap directly onto the surface of the pudding to prevent a skin from forming. Chill in the refrigerator for at least 3 hours, or until fully set.
