Tips and Tricks: How To Thicken Caramel Sauce

Do not use hot water with these thickeners; especially on starches, because they result in lumps in hot water. The quantity of each thickener is distinct from one another. So, it is best to check the step-by-step instructions cautiously. Add or remove the sauce that does not attain the desired thickness. Likewise, ensure to dissolve the mixture of thickener and water entirely before adding it to the caramel sauce to avoid clumping.

If you do not have a sweet tooth, you can add a tiny bit of salt to the caramel sauce to lessen the sweetness or avoid using extra sugar at the very least when thickening the caramel sauce. After making the caramel sauce, let it rest for a bit to check if the consistency reached what you desired it to be since caramel sauce is more likely to thicken better when it has been cooled.

Caramel sauce can be frozen in an airtight container made of plastic that could last up to three months. Ensure to defrost the caramel sauce overnight in the refrigerator and gradually warm it before using it. Thawed caramel sauce can be used within two days. 

What Do I Do if My Caramel is Too Runny?

If your caramel is too runny, there are a range of ways you can salvage it and make it thicker. Let’s take a closer look at some of the ways you can achieve this.

  • Make a Slurry. Slurries are one of the easiest ways to thicken most foods, including caramel. All you need to do is add equal parts water and equal parts starch (such as cornstarch or tapioca starch) to a bowl and mix well. Then gradually add the slurry to your caramel until you reach the consistency you’re looking for.
  • Time. Another way to thicken your caramel is simply to leave it on the stove for longer. The longer it heats, the thicker it will become. However, it’s important not to burn your caramel. You should keep a watchful eye on your caramel at all times.
  • Use Heavy Cream. Add some heavy cream to your caramel and then place it back onto the stove over low heat, until the caramel begins to thicken.
  • Make More. Another way to thicken your caramel is to simply make more and add it to your first batch of caramel. However, you’ll need to ensure that your second batch is thicker than your first.

  • Use a Microwave. This is the quickest way to soften your caramel. All you need to do is add the caramel to a microwave-safe covered container and heat for around 20-30 seconds. If it needs longer, heat for another 10 seconds or so at a time. After this point, it should be softer.
  • Use a Slow Cooker. This is the most time-consuming method, but it can make for the most delicious caramel. Place your caramel into a slow cooker and heat on low for around 4-6 hours, or heat on high for around an hour. Remove from the cooker and leave to cool before eating, or storing.
