When it comes to preserving the freshness and flavor of your homemade jam, thickening it with cornstarch is a popular and effective method. Freezer jam, in particular, requires a special technique to achieve the perfect consistency, as it’s designed to be stored in the freezer and consumed over a longer period. In this comprehensive guide, we’ll explore the importance of thickening freezer jam with cornstarch, the benefits of using this method, and provide step-by-step instructions on how to do it successfully.
The Importance of Thickening Freezer Jam
Freezer jam is a type of jam that’s made with a lower sugar content and a higher pectin content than traditional jam. This is because pectin, a natural occurring substance found in fruit, helps to thicken the jam and give it a gel-like consistency. However, when you store freezer jam in the freezer, the pectin can break down over time, causing the jam to become too runny. This is where cornstarch comes in – it helps to restore the jam’s original consistency and texture.
Benefits of Thickening Freezer Jam with Cornstarch
Thickening freezer jam with cornstarch offers several benefits, including:
- Improved texture: Cornstarch helps to restore the jam’s original texture, making it more spreadable and easier to use.
- Extended shelf life: By thickening the jam, you can extend its shelf life and prevent it from becoming too runny or watery.
- Easier to use: Thickened jam is easier to use in recipes and for topping toast, yogurt, or ice cream.
- Better flavor: Cornstarch doesn’t affect the flavor of the jam, allowing you to enjoy the natural taste of the fruit.
How to Thicken Freezer Jam with Cornstarch
To thicken your freezer jam with cornstarch, you’ll need the following ingredients:
- 1 cup of freezer jam
- 2 tablespoons of cornstarch
- 2 tablespoons of water
- Optional: lemon juice or zest, spices, or other flavorings
Here’s a step-by-step guide on how to thicken your freezer jam with cornstarch:
Step 1: Mix the Cornstarch and Water
In a small bowl, whisk together the cornstarch and water until smooth. Make sure to whisk in one direction only to avoid creating lumps.
Step 2: Add the Cornstarch Mixture to the Jam
Add the cornstarch mixture to the freezer jam and whisk until well combined. Make sure to whisk in one direction only to avoid creating lumps.
Step 3: Cook the Jam
Place the jam in a saucepan and cook over medium heat, whisking constantly, until the jam comes to a boil. Reduce the heat to low and simmer for 5-7 minutes, or until the jam has thickened to your liking.
Step 4: Remove from Heat and Let Cool
Remove the jam from the heat and let it cool to room temperature. This will help the jam to thicken further and prevent it from becoming too runny.
Step 5: Store the Jam
Once the jam has cooled, transfer it to an airtight container and store it in the refrigerator for up to 6 months or in the freezer for up to a year.
Tips and Variations
Here are some tips and variations to keep in mind when thickening your freezer jam with cornstarch:
- Use a low heat: Cooking the jam over low heat will help to prevent the cornstarch from breaking down and creating a grainy texture.
- Whisk constantly: Whisking the jam constantly while it’s cooking will help to prevent lumps from forming and ensure a smooth texture.
- Adjust the ratio: You can adjust the ratio of cornstarch to water to achieve the desired consistency. A general rule of thumb is to use 1 tablespoon of cornstarch per 1 cup of jam.
- Experiment with flavors: You can add different flavorings, such as lemon juice or zest, spices, or other fruits, to create unique and delicious flavor combinations.

In this comprehensive guide, we’ve explored the importance of thickening freezer jam with cornstarch, the benefits of using this method, and provided step-by-step instructions on how to do it successfully. By following these simple steps and tips, you can achieve the perfect consistency for your homemade jam and enjoy it for months to come.
Frequently Asked Questions
Q: Can I use other thickeners instead of cornstarch?
A: Yes, you can use other thickeners, such as tapioca starch or arrowroot powder, but cornstarch is the most common and effective thickener for jam. Make sure to follow the same ratio and instructions as with cornstarch.
Q: How do I know if my jam is too thick or too thin?
A: If your jam is too thick, it may be difficult to spread or may have a grainy texture. If it’s too thin, it may be too runny or watery. You can adjust the ratio of cornstarch to water or cook the jam for a longer period to achieve the desired consistency.
Q: Can I thicken jam that’s already been cooked?
A: Yes, you can thicken jam that’s already been cooked, but it may not be as effective as thickening it before cooking. You can try adding a small amount of cornstarch mixture to the jam and whisking it until well combined, then cooking it for an additional 5-7 minutes to achieve the desired consistency.
Q: How do I store thickened jam?
A: Thickened jam can be stored in an airtight container in the refrigerator for up to 6 months or in the freezer for up to a year. Make sure to label the container with the date and contents and store it in a cool, dark place.
Q: Can I use thickened jam in recipes?
A: Yes, you can use thickened jam in recipes, such as baked goods, sauces, or as a topping for yogurt or ice cream. Make sure to adjust the amount of jam according to the recipe and the desired consistency.
