Berry syrup, maple syrup, or simple syrup all add a touch of sweetness to breakfasts or desserts. Making your own syrup is a fun recipe to try, but if your syrup is too thin or watery, it may not stick to your food the way you’d like it to. You can use items from your kitchen to thicken it up within 30 minutes to get gooey, delicious syrup that your friends and family will love.

Method 1 of 3:

Reducing the Syrup

Download Article

  1. 1

    Pour your syrup into a saucepan on low heat. Choose a wide saucepan with high sides for a quicker reduction and keep the heat low so you don’t burn your syrup. The more syrup you put in your saucepan, the longer it will take to reduce.[1]

    • If you have a lot of syrup you want to thicken up, you can use 2 saucepans.

    Simmer your syrup for 10 minutes as you stir it occasionally. Keep the heat down low and use a wooden spoon to stir your syrup occasionally for 10 to 15 minutes. If it starts to boil, turn the heat down so that it doesn’t get too hot.[2]

    • Leave your saucepan uncovered so that the liquid has somewhere to evaporate.

  3. 3

    Use a candy thermometer to monitor the temperature until it reaches 223°F (106°C). Use a candy thermometer to check the temperature in the middle of your saucepot. Once it reaches between 223 and 230°F (106 and 110°C), it will be thick enough to stick to pancakes or cake.[3]

    • Keep your syrup below 241°F (116°C) so that it doesn’t get too thick.
  4. 4

    Take your syrup off the heat when it is hot enough. Turn off the heat and let your syrup cool down for about 2 minutes. Serve your syrup while it’s still warm, and use it to sweeten up pancakes, french toast, or ice cream.[4]

    Tip: You can track the level of your syrup by finding the mark that the syrup made on the sides of the saucepan when it was first poured in.

Method 2 of 3:

Using Cornstarch

  1. 3 Ways to Thicken Syrup - wikiHow (9)

    1

    Make a 1:1 ratio of cornstarch and water. In a small bowl, combine equal amounts of cornstarch and warm water, starting with 3 tablespoons (44mL) of each. Mix them together with a spoon until they form a gritty paste.[5]

    • Cornstarch is a thickening agent that won’t change the flavor of your syrup.
  2. 2

    Put the syrup in a saucepan over low heat. Choose a wide saucepan and pour all of your syrup into it. Turn your heat on low and wait for small bubbles to form in your syrup, stirring it occasionally.[6]

    • Don’t let your syrup boil. If you start to see large bubbles, turn down the heat.

    3

    Pour 1UStbsp (15mL) of the mixture into the syrup and stir it. Start out with a little bit of your cornstarch mixture to see how it combines with the syrup. Use a wooden spoon to mix the cornstarch and the syrup together, and keep an eye on the thickness.[7]

    • If you are thickening a light-colored berry syrup, cornstarch may make it look more dull or grainy.
  4. 3 Ways to Thicken Syrup - wikiHow (12)

    4

    Add more cornstarch mixture if you need to 1 tablespoon (15mL) at a time. Depending on how thick you’d like your syrup, you can keep adding the cornstarch mixture 1UStbsp (15mL) at a time every 5 minutes or so. Stir it into your syrup until it is thick enough for your liking.[8]

    Tip: To test that the syrup is thick enough to stick onto pancakes or waffles, dip a spoon into the syrup and then hold it above the saucepan. If the syrup falls off the spoon in slow ribbons, it is thick enough.

  5. 5

    Take your syrup off the heat and serve it while it is warm. Drizzle your syrup over breakfast or dessert items. If you want to save your syrup, wait until it cools down and then store it in an airtight container for 2 to 3 days.[9]

    • Syrup tastes the best when it is eaten fresh.

Adding Gelatin

  1. 1

    Simmer your syrup for 10 minutes on medium heat. Put your syrup in a wide, deep saucepan with high sides and turn your stovetop to medium heat. Allow your syrup to simmer for about 10 minutes, stirring it occasionally so that the bottom doesn’t burn.

    • Gelatin works the best in liquids that have already been warmed up.

    2

    Take your syrup off the heat. Turn the stovetop off and move the saucepot off the hot burner. Set it to the side and let the syrup sit for about 1 minute to cool down slightly.

    Tip: Don’t leave your syrup for longer than 1 minute, or it could start to harden up again.

  3. 3 Ways to Thicken Syrup - wikiHow (17)

    3

    Add 1 tbsp (14 g) of powdered gelatin to your syrup. Use a powdered, flavorless gelatin and stir it in with a wooden spoon for about 2 minutes. Make sure you let it dissolve completely so that you can’t see any of the powder left in your syrup.[10]

    • Flavorless gelatin won’t change the taste of your syrup.
    • You can find flavorless gelatin at most grocery stores.

    4

    Keep adding gelatin in 1 tablespoon (14.8ml) (14 g) increments if you need to. If your syrup isn’t thick enough after your first round of gelatin, keep adding more and stirring it in about every 5 minutes. Serve your syrup when it’s warm for the best flavor.[11]

      Article SummaryX

      To thicken syrup without any additives, simply reduce it on the stove. Pour the syrup into a saucepan, then turn the burner on low. Bring the sauce to a low simmer and let it sit for about 10 minutes, stirring occasionally so it doesn’t burn. Leave the lid off so that some of the liquid can evaporate, which is what will cause the syrup to thicken. Test the syrup with a candy thermometer after about 10 minutes. Once it gets to around 223 degrees Fahrenheit, the syrup should be thick enough. Let it cool down for 2 minutes before drizzling it over pancakes or waffles.
