Delicious Rhubarb Pineapple Jam Ingredients
For the Jam
• Rhubarb – Cut into 1/2-inch pieces for the perfect tart base. Fresh rhubarb is optimal; if unavailable, frozen (thawed and drained) is acceptable.
• Crushed Pineapple – 20 oz, preferably Dole, adds essential sweetness and moisture; use with its juice for the best consistency.
• Sugar – 1.75 cups is crucial for sweetening and achieving that glorious syrupy texture. No substitutions recommended here!
• Strawberry Gelatin – 6 oz (preferably Jell-O brand) helps your jam to set and ensures a firm, spreadable consistency; avoid adding it to the boiling mixture directly.
• Lemon Juice – 1 tablespoon brightens the flavors and balances the sweetness, ensuring a zesty kick. No substitutions noted.
Each ingredient plays a vital role in creating your Delicious Rhubarb Pineapple Jam. Now that you’re ready with the ingredients, let’s get that pot simmering!
Step‑by‑Step Instructions for Delicious Rhubarb Pineapple Jam
Step 1: Prepare the Rhubarb
Start by washing your fresh rhubarb stalks, then chop them into uniform 1/2-inch pieces. This ensures that they cook evenly and develop that delightful tangy flavor. Set them aside as you gather the remaining ingredients for your Delicious Rhubarb Pineapple Jam.
Step 2: Combine Ingredients
In a large, heavy-bottomed pot, combine your prepared rhubarb with 20 ounces of crushed pineapple (including its juice) and 1.75 cups of sugar. Allow the mixture to sit for about 2 to 3 minutes, letting the sugar dissolve and the flavors meld together beautifully before moving on to the next step.
Step 3: Heat Mixture
Place the pot over medium-high heat and bring the mixture to a gentle boil. Stir frequently to prevent any ingredients from sticking to the bottom of the pot. As it heats, watch for the bubbling action in the jam—this indicates it’s time to move forward in creating your perfect Delicious Rhubarb Pineapple Jam.
Step 4: Boil and Thicken
Once boiling, reduce the heat slightly and continue to boil the jam, stirring constantly, for about 20 minutes. During this time, the mixture will thicken and transform into a luscious, jam-like consistency. Keep your eyes on the pot, as it can bubble up and potentially splatter.
Step 5: Add Lemon Juice
After 15 minutes of boiling, add 1 tablespoon of lemon juice to the pot. This brightens up the flavors in your Delicious Rhubarb Pineapple Jam and balances the sweetness from the sugar and pineapple. Stir well to incorporate the lemon juice evenly throughout the mixture.
Step 6: Incorporate Gelatin
Once the cooking time is complete, remove the pot from heat and immediately sprinkle in 6 ounces of strawberry gelatin over the hot jam. Stir vigorously for about 2 minutes until the gelatin fully dissolves, ensuring a fabulous texture in your final product without any lumps.
Step 7: Jar the Jam
Carefully ladle the hot jam into sterilized jars, leaving about 1/4 inch of headspace at the top of each jar. Be careful with the hot mixture and avoid spills. This step is crucial for preserving your Delicious Rhubarb Pineapple Jam so it can be stored properly.
Step 8: Cool and Set
Allow your filled jars to cool at room temperature for about 30 minutes before sealing. Once cooled, refrigerate the jam for at least 4 hours or overnight to set completely. After this time, your Delicious Rhubarb Pineapple Jam will be ready to enjoy, bursting with vibrant flavors!
