Ingredients for Strawberry Rhubarb Jam

4 1/2 cups mashed strawberries (hulled)
1 1/2 cups rhubarb, diced into 1/2 inch chunks
1 packet pectin crystals (like certo or sure-jell)
6 1/2 cups white sugar
1 teaspoon butter (optional, for less foam)

How to Make Strawberry Rhubarb Jam: Step-by-Step

Creating this jam is a process, a rhythm of stirring, watching, and waiting. Each step contributes to the final product, a testament to the time and care invested.

Prepare the Fruit: Gently wash and hull the strawberries. Mash them using a potato masher or in a food processor until you have 4 1/2 cups. Dice the rhubarb into small, even pieces, about 1/2 inch in size. Having uniformly sized pieces ensures even cooking.
Combine Ingredients: In a large, heavy-bottomed pot, combine the mashed strawberries, diced rhubarb, and pectin crystals. Stir well to ensure the pectin is evenly distributed. This is crucial for proper setting.
Bring to a Boil: Place the pot over medium-high heat and bring the mixture to a full rolling boil that you can’t stir down. A full rolling boil is essential for activating the pectin and achieving the correct jam consistency. Add the butter, if using, to reduce foaming.
Add Sugar: Once the mixture is at a full rolling boil, quickly add all the sugar. Stir constantly to dissolve the sugar completely. Ensuring the sugar dissolves properly prevents a grainy texture in the final jam.
Boil Again: Return the mixture to a full rolling boil, stirring constantly. Boil hard for exactly 1 minute. Use a timer to ensure accuracy. Overcooking can result in a tough jam, while undercooking can prevent it from setting.
Test for Setting: Remove the pot from the heat. To test if the jam is ready, place a small spoonful on a chilled plate. Let it sit for about 30 seconds, then push it with your finger. If it wrinkles, the jam is set. If it’s still runny, return the pot to the heat and boil for another minute, then test again.
Process the Jars: If you intend to can the jam, prepare your canning jars by sterilizing them. There are several ways to sterilize the jars. You can boil the jars and lids for 10 minutes, or run them through a sanitize cycle in your dishwasher. Keep the jars hot until ready to fill.
Fill the Jars: Ladle the hot jam into the sterilized jars, leaving 1/4 inch headspace at the top. Wipe the rims of the jars clean with a damp cloth. This is important to ensure a good seal. Place the lids on the jars and screw on the bands fingertip tight.
Process in a Water Bath Canner: Place the filled jars in a water bath canner. Ensure the jars are covered by at least 1 inch of water. Bring the water to a boil and process for 10 minutes. Adjust processing time for altitude if necessary.
Cool and Check Seals: Carefully remove the jars from the canner and place them on a towel-lined surface to cool completely. As the jars cool, you should hear a popping sound as the lids seal. After the jars have cooled, check the seals by pressing down on the center of each lid. If the lid doesn’t flex, it’s sealed. If a lid flexes, it’s not sealed, and the jar should be refrigerated and used within a few weeks.

Pro Tips for Perfect Strawberry Rhubarb Jam

These are the little secrets passed down through generations, the nuances that elevate a good jam to an exceptional one.

Use Ripe Fruit: The best jam starts with the best ingredients. Use ripe, but not overripe, strawberries and rhubarb for the most flavorful results.
Chop Rhubarb Evenly: Consistent rhubarb size ensures even cooking.
Don’t Reduce Sugar: Sugar is not just for sweetness; it’s also a preservative. Reducing the sugar can affect the jam’s set and shelf life.
Use a Heavy-Bottomed Pot: This helps prevent scorching and ensures even heat distribution.
Stir Constantly: This prevents the jam from sticking to the bottom of the pot and burning.
Test the Set: Don’t skip the cold plate test! It’s the most reliable way to determine if your jam is ready.

Common Mistakes to Avoid When Making Strawberry Rhubarb Jam

Even seasoned jam makers can fall prey to these common pitfalls. Being aware of them is half the battle.

Not Using Enough Pectin: Pectin is essential for thickening the jam. Make sure to use the correct amount specified in the recipe.
Overcooking the Jam: Overcooking can result in a tough, rubbery jam. Follow the cooking times carefully and test for setting frequently.
Undercooking the Jam: Undercooking can result in a runny jam that doesn’t set properly. Make sure to boil the jam for the specified time and test for setting.
Not Sterilizing Jars Properly: Improperly sterilized jars can lead to spoilage. Always sterilize your jars and lids before filling them with jam.
Leaving Too Much Headspace: Leaving too much headspace in the jars can prevent them from sealing properly. Make sure to leave the correct amount of headspace, usually 1/4 inch.

Strawberry Rhubarb Ginger Jam: Add 1-2 tablespoons of grated fresh ginger to the pot along with the fruit. The ginger adds a warm, spicy note that complements the sweetness of the jam.

Spiced Strawberry Rhubarb Jam: Add 1/2 teaspoon of ground cinnamon and 1/4 teaspoon of ground nutmeg to the pot along with the fruit. The spices add a warm, festive flavor.
