Step 1

Heat the sugar in a pot with high sides under medium heat. Stir it often with a whisk, especially as it clumps and then melts. Once melted, continue whisking until it turns a medium-dark amber color. You may need a silicone spatula to pull the sugar off the sides as it melts.

Step 2

Once the sugar is melted and amber-colored, add in the butter chunks and continue whisking as the mixture bubbles up..

Step 3

Once the sugar and butter are combined, take the mixture off the heat and slowly stir in the heavy cream. Whisk the sauce continuously. It bubbles up again and then smooths out.

Step 4

Then add in the sea salt and whisk it until well combined.

Step 5

Pour into one or more heat-resistant glass jars and refrigerate.
