Homemade Strawberry Rhubarb Jam – A delightful and simple jam recipe crafted with fresh, seasonal strawberries and rhubarb.

Homemade Strawberry Rhubarb Jam: Capturing Summer’s Essence in a Jar
Even as the year draws to a close, my mind often drifts back to the vibrant flavors of summer, and this rich, sweet, and wonderfully tart Strawberry Rhubarb Jam is a perfect embodiment of those cherished memories. While strawberries and rhubarb might be long out of season by December, the joy of preserving summer’s bounty ensures we can savor these delightful tastes year-round. This particular recipe, a true family favorite, was actually crafted back in the peak of June’s harvest, capturing the sun-ripened sweetness of strawberries and the intriguing tang of fresh rhubarb at their very best. The simple pleasure of making and enjoying homemade jam is a timeless tradition, transforming fleeting seasonal produce into a lasting treat.
Making jam is more than just cooking; it’s an act of preserving. It’s about transforming ephemeral fresh fruit into something lasting, a spoonful of sunshine on a cold winter morning. There’s a profound satisfaction in opening a jar of homemade jam, knowing every ingredient was chosen with care, often plucked directly from a garden. For this recipe, the strawberries and rhubarb came straight from my in-laws’ flourishing garden – a secret ingredient that truly elevates the flavor to something you simply cannot replicate with store-bought produce. That unparalleled freshness makes all the difference, resulting in a jam so exquisite, my husband declared it his all-time favorite. It’s the kind of simple, pure flavor that brings comfort and joy, reminding us of nature’s generous bounty.
Why Strawberry and Rhubarb Are a Match Made in Heaven
The combination of strawberry and rhubarb is a time-honored classic for good reason, beloved by home cooks and gourmet chefs alike. Strawberries, with their juicy sweetness, floral aroma, and delicate texture, perfectly complement the unique tartness and fibrous texture of rhubarb. Rhubarb, often mistaken for a fruit but botanically a vegetable, brings a crisp, tangy counterpoint that prevents the jam from becoming overly sugary or cloying. When cooked together, they create a harmonious balance of flavors – sweet, sour, and utterly refreshing. This dynamic duo offers a nostalgic taste that reminds many of childhood desserts, pies, and crumbles, now lovingly transformed into a spreadable delight. It’s a flavor profile that evokes warmth, sunshine, and home.
Beyond their complementary tastes, both ingredients contribute beautifully to the jam’s texture and color. Strawberries break down into soft, sweet chunks, releasing their vibrant red juices, while rhubarb softens into tender strands, creating an inviting consistency that’s neither too smooth nor too lumpy. The vibrant red of the strawberries, enhanced by the subtle pinks and greens of the rhubarb, results in a jam that is as visually appealing as it is delicious, a true feast for the senses. This visually striking hue makes it a lovely gift and an attractive addition to any breakfast table or dessert plate.
The Rewards of Crafting Your Own Homemade Jam
While making jam might seem like a daunting task to some, it’s an incredibly rewarding culinary experience. There’s a distinct pride in presenting a homemade jar, filled with natural goodness, free from artificial preservatives or excessive additives often found in commercial products. You have complete control over the sweetness level, allowing you to tailor the jam to your personal preference, and you can hand-select the quality of your ingredients. This hands-on process connects you directly to the food you eat, deepening your appreciation for fresh produce and traditional kitchen skills. And let’s be honest, the incredibly fragrant aroma that fills your kitchen as the fruit simmers and transforms is reason enough to embark on this delicious culinary adventure! It’s a sensory journey that culminates in a pantry stocked with delicious, wholesome preserves.
Tips for Sourcing the Best Ingredients for Your Jam
- Strawberries: Always look for ripe, firm, and intensely fragrant berries. Local farmers’ markets, roadside stands, or pick-your-own farms are ideal sources, offering the freshest and most flavorful options. If fresh isn’t available, quality frozen strawberries (thawed) can be a suitable alternative, though fresh will always yield the best flavor and texture.
- Rhubarb: Choose crisp, firm stalks that are vibrant in color, whether red or greenish-pink. Avoid any stalks that appear limp, bruised, or discolored, as these indicate a lack of freshness. Homegrown rhubarb, like the kind from my in-laws’ garden, truly makes this jam shine with an unparalleled freshness and a more robust flavor profile. Remember that only the stalks are edible; the leaves are poisonous and should be discarded.
- Lemons: Freshly squeezed lemon juice is crucial not only for its bright, tangy flavor but also for its natural pectin and acidity, which play a vital role in setting the jam and enhancing its shelf life. Do not use bottled lemon juice if possible, as its flavor is often inferior and it may lack the natural pectin content needed.
Understanding Pectin and Mastering the Setting Point
Pectin is a naturally occurring soluble fiber found in fruits that acts as a gelling agent. It’s what gives jams and jellies their characteristic firm, spreadable texture. Some fruits, like apples and citrus, are naturally high in pectin, while others, like strawberries and rhubarb, benefit from added commercial pectin to ensure a reliable and firm set. This recipe specifically uses powdered fruit pectin to guarantee a consistent and desirable texture, transforming the cooked fruit mixture into a perfectly spreadable jam rather than a runny sauce. Understanding pectin is key to successful jam making, preventing frustratingly soft or overly stiff results.
Achieving the “setting point” is the critical step in jam making. This is the moment when the jam has reached the ideal concentration of sugar, acid, and pectin to gel properly. There are several reliable ways to test for the setting point:
- The Cold Plate Test: Before you start cooking, place a small ceramic plate or saucer in the freezer. When you think the jam is ready, spoon a small amount onto the chilled plate. Let it sit for a minute to cool, then push it gently with your finger. If the surface wrinkles, the jam is set and ready to be removed from the heat.
- Temperature Test: For a more precise method, use a candy thermometer to monitor the jam’s temperature. Most fruit jams set at around 220°F (104°C) at sea level. It’s important to adjust this temperature for higher altitudes (subtract 2°F for every 1,000 feet above sea level).
- The Sheet Test: Dip a cold metal spoon (chilled in ice water) into the jam and lift it out, holding it horizontally. Allow the jam to drip off the side of the spoon. If the jam forms a “sheet” or a few thick drops that cling together rather than individual, watery drops, it’s a good indication that it’s set.
Don’t be afraid to experiment with these methods or use a combination of them. Practice makes perfect, and even if your jam is a little softer than intended on your first try, it will still be absolutely delicious and perfect for pouring over pancakes or ice cream!

Pin Recipe
Ingredients
- 3 cups of strawberries, stems removed, halved if large
- 2 cups rhubarb, cleaned and sliced into 1/2-inch pieces
- Juice of 2 freshly squeezed lemons (approx. 1/4 to 1/3 cup)
- 7 cups granulated sugar
- 1 pkg. fruit pectin (standard 1.75 oz / 49g box, e.g., Sure-Jell or Ball RealFruit)
- 1-2 teaspoons unsalted butter (optional, helps reduce foam)
Instructions
Prepare the Fruit Mixture: In a large, heavy-bottomed pot or Dutch oven (at least 6-quart capacity), combine the prepared strawberries, sliced rhubarb, and fresh lemon juice. Stir gently to ensure the fruit is evenly coated.
Simmer Fruit: Place the pot over gentle to medium-low heat. Simmer the fruit mixture for about 15-20 minutes, stirring occasionally, until the fruit has softened significantly and collapsed. The mixture should be tender and somewhat broken down, but still retain some texture.
Add Pectin and Sugar: Once the fruit is softened, stir in the granulated sugar, fruit pectin, and unsalted butter (if using). Stir constantly over medium heat until the sugar is completely dissolved. This step is crucial to prevent the pectin from clumping and the sugar from scorching.
Bring to a Rapid Boil: Increase the heat to high. Bring the mixture to a rapid, rolling boil that cannot be stirred down. This is important for activating the pectin. Boil vigorously for 10-20 minutes, or until the jam reaches its desired setting point. Use one of the setting tests (cold plate, temperature, or sheet test) described above to confirm it’s ready.
Cool and Skim: Carefully remove the pot from the heat. Let the jam cool for 8-10 minutes. During this brief cooling period, any foam that has formed on the surface will rise. Skim off any foam using a large spoon or ladle for a clear, attractive jam. While harmless, foam can make the jam cloudy.
Jar the Jam: Ladle the hot jam into warmed, sterilized canning jars, leaving about 1/4 inch headspace (the space between the jam and the rim of the jar). Wipe the rims clean with a damp cloth to ensure a proper seal. Place wax disks directly on the surface of the jam (optional, but a traditional step for some home canners). Secure with new, sterilized two-piece canning lids and bands, finger-tight.
Process Jars (Optional but Recommended for Shelf Stability): For shelf-stable jam that can be stored at room temperature, process the filled jars in a boiling water bath for 10 minutes (refer to reliable canning guides for specific processing times based on your altitude). Carefully remove jars from the water bath and let them cool completely and undisturbed on a towel on the counter for 24 hours. Check seals; if the lids are concave and don’t flex when pressed, they are sealed. Any unsealed jars should be refrigerated and consumed within a few weeks.
Store: Once completely cool and sealed, label the jars with the date of preparation and store them in a cool, dark pantry or cupboard away from direct sunlight or heat. Properly canned jam can last for up to a year. Always refrigerate jars after opening.
Recipe Notes:
This recipe is adapted from “Jams and Preserves” (link to book).
For best results, use a wide, shallow pot for boiling jam. This increases the surface area, allowing the liquid to evaporate faster and reducing overall cooking time, which helps preserve the fresh fruit flavor.
Sterilizing jars is crucial for safe, long-term storage. You can boil them in hot water for 10 minutes, use a dishwasher’s sanitize cycle, or bake them in a low oven (225°F / 110°C) for 20 minutes. Ensure jars are hot when filling with hot jam to prevent thermal shock.

A Note on Canning and Safe Storage Practices
Proper canning techniques are not just about aesthetics; they are absolutely essential for ensuring the safety and shelf stability of your homemade jam. While this recipe provides detailed instructions for making the jam, following established canning guidelines for processing in a boiling water bath is highly recommended for long-term storage outside the refrigerator. This critical process ensures that any potential spoilage organisms are neutralized, creating a strong vacuum seal that keeps your jam fresh, safe, and delicious for up to a year or even more. Always consult a reputable canning guide (like those from the National Center for Home Food Preservation) for comprehensive safety information.
Always inspect your jars for a proper seal after they cool completely (typically after 12-24 hours). The center of the lid should be concave and should not flex when pressed. If a jar doesn’t seal properly, simply refrigerate it and enjoy its contents within a few weeks. Store sealed jars in a cool, dark pantry or cupboard, away from direct sunlight or any sources of heat, which can degrade the jam’s quality and color over time. Proper storage ensures you can enjoy the taste of summer for months to come.
