Ingredients for a good recipe for caramel sauce include 1 cup of white sugar, 5 tablespoons of butter, 1/2 cup of heavy cream, 1 tablespoon of heavy whipping cream and 1 pinch of sea salt, to taste. This recipe, featured and highly rated on AllRecipes.com, takes about 25 minutes to prepare and yields eight servings.
Put the sugar into a heavy-bottomed saucepan, and stir it continuously over medium-high heat for about 10 minutes while it melts. When the sugar has completely melted and darkened, stop stirring the sugar, but continue to cook it for another three to eight minutes or until it becomes a dark shade of amber and begins to smoke. Remove the saucepan from heat and wait about 30 seconds.
Whisk in the butter until it melts completely. Slowly pour in the heavy cream, followed by the whipping cream. Ensure the sauce does not bubble over while doing so. If you desire a salted caramel sauce, stir in the sea salt. Pour the sauce into a jar, allow it to cool completely, and refrigerate it.
For a simpler approach to caramel sauce, simply simmer an unopened can of sweetened condensed milk in a pot for approximately three hours.
