Salted Caramel Sauce

Caramel sauce might be one of Hubby’s favorite things ever. He will always choose a caramel treat over a a chocolatey treat. I’ve just recently gotten more comfortable making my own caramel sauce. It actually is so much easier than I thought it was. Having a candy thermometer is a must for making caramel at home. But that’s really all you need. If you haven’t made your own caramel sauce, do it. Trust me, it’s worth the minimal effort required.

I ended up making a triple batch of this salted caramel during the holidays. I ordered some cute jars online and gave them away as gifts to some family members. Hubby also enjoyed a bunch of this caramel sauce heated up over vanilla ice cream.

Salted Caramel Sauce

Salted caramel sauce is easier to make than you could ever imagine. And it makes a great gift!

Yield: 2 cups


1 cup water
2 cups sugar
1 cup heavy cream
2 Tbsp cold unsalted butter
1 tsp fleur de sel


Add water to a 2-qt saucepan. Gently add the sugar to the center of the pot - it will mound, that's fine. Cover the pot and bring to a boil over high heat.

Once boiling, uncover the pot and insert a candy thermometer. Continue cooking until the mixture registers 300 F and is just starting to develop some color, about 15 minutes.

Reduce heat under the pot to medium and cook until the syrup is amber and registers 350 F on the thermometer, about another 5 minutes.

Meanwhile, pour the cream into a small saucepan and bring to a simmer. If it simmers before the syrup is ready, just take it off the heat and set aside.

Remove the caramel from the heat and add about 1/4 of the warm cream to the pot. It will bubble furiously so be careful. Once the bubbling subsides, add the remaining cream. When it stops bubbling, whisk gently to incorporate fully. Add the butter and the salt and whisk to combine.

Refrigerate up to 1 month.

    How big a bottle of Guinness, please? (I’m not a beer person and I never stock beer so I’d really love to know, please!)

    Can’t wait to try this recipe. Thank you, and warm regards,

      Sorry, I’ll update the recipe. A bottle of Guinness has 11.2oz in it.

    Now if only I knew where to procure mustard seeds from… I love mustard and would love to make some at home, too!

      I buy mine at Penzey’s. We have one really close to our house in Cincinnati now, but they also have a website you can order from. Or you could check out Amazon.

    I bookmarked this. I’ve been wondering how to make mustard from scratch. Thanks!

    • beantownbaker — July 16th, 2013 @ 8:36 am

      It’s definitely worth making at home!

    My boyfriend loves Guinness mustard. We used to be able to buy it from a farm shop in the UK, but I think they’ve stopped making it. So glad I found this recipe, I made it last night. Can’t wait to see how it turns out. Thanks so much for posting!
