1. Heat granulated sugar in a medium heavy-duty stainless steel saucepan (do not use nonstick) over medium heat, stirring constantly with a high heat-resistant silicone spatula or wooden spoon. Sugar will form clumps and eventually melt into a thick brown, amber-colored liquid as you continue to stir. On my stove, this takes about 6 minutes. Be careful not to burn it.
2. Once sugar is completely melted, immediately stir in the butter until melted and combined. Be careful in this step because the caramel will bubble rapidly when the butter is added. If you notice the butter separating or if the sugar clumps up, remove from heat and vigorously whisk to combine it again. (If you’re nervous for splatter, wear kitchen gloves. Keep whisking until it comes back together, even if it takes 3–4 minutes. It will eventually—just keep whisking. Return to heat when it’s combined again.)
3. After the butter has melted and combined with the caramelized sugar, stir constantly as you very slowly pour in the heavy cream. Since the heavy cream is colder than the hot caramel, the mixture will rapidly bubble when added. After all the heavy cream has been added, stop stirring and allow to boil for 1 minute. It will rise in the pan as it boils. If you’d like to be precise and use a candy thermometer, the temperature will rise to about 220°F (104°C).
4. Remove from heat and stir in the salt. The caramel will be a thin liquid at this point. Allow to slightly cool down before using. Caramel thickens as it cools.
5. Cover tightly and store for up to 1 month in the refrigerator. Caramel solidifies in the refrigerator. Reheat in the microwave or on the stove to desired consistency.
