Step 1

Put the sugar, cornstarch and kosher salt in a medium, nonstick saucepan, then gently whisk together. Put the milk and egg yolks in a separate pitcher or bowl, then whisk together until combined. Pour the wet mixture into the saucepan with the dry ingredients and stir to combine.

Step 2

Turn on the heat to medium and cook, stirring gently, until the mixture starts to bubble and thicken, about 10 minutes. When it reaches a pudding consistency, add the butter and stir until melted. Remove from the heat and spoon into bowls. Chill for about 1 hour, until very cold.

Step 3

Top each bowl with about a tablespoon of salted caramel sauce, some sea salt flakes and unsweetened whipped cream.
