Ingredients You’ll Need

- 4 cups fresh rhubarb: Chopped into small pieces to cook evenly and release its signature tang.
- 2 cups granulated sugar: Essential for preservation and perfectly balancing rhubarb’s tartness.
- 2 tablespoons fresh lemon juice: Adds brightness and balances the jam’s sweetness beautifully.
- 1 tablespoon lemon zest: Enhances the flavor, bringing an extra burst of citrus aroma.

How to Make Rhubarb and Lavender Jam: A Sweet Floral Preserve for Toast Recipe
Step 1: Prepare Your Ingredients
Start by washing and chopping the rhubarb into small, uniform pieces—it helps the rhubarb cook evenly. If you’re using fresh lavender instead of dried, gently remove the buds from their stems and give them a quick rinse to remove any dirt or impurities.
Step 2: Steep the Lavender
Bring ½ cup of water to a gentle simmer in a small saucepan, then remove it from heat and stir in the lavender. Let it steep for about 5 minutes, allowing the water to soak up that lovely floral essence. After steeping, strain out the lavender buds so your jam remains smooth.
Step 3: Combine the Base Ingredients
In a larger saucepan, combine the chopped rhubarb, sugar, fresh lemon juice, lemon zest, and your lavender-infused water. Heat the mixture over medium heat, stirring occasionally to help the sugar dissolve and the flavors blend harmoniously.
Step 4: Simmer to Perfection
Bring this blend to a gentle boil, then reduce the heat to low and let it simmer for 25 to 30 minutes. Stir occasionally to prevent sticking and to keep the jam cooking evenly. The rhubarb will break down, and the mixture will begin to thicken into that perfect jam consistency.
Step 5: Test and Finish
To check if your jam is ready, place a small spoonful on a chilled plate and push it gently—if it wrinkles, the jam is done! Stir in the vanilla extract, which will add a comforting warmth to your preserve.
Step 6: Jar and Store
Carefully pour the hot jam into sterilized jars, seal them up, and allow the jars to cool. Once cooled, you can refrigerate the jam for up to 3 weeks or use a water bath canning method for longer storage. This process locks in all that deliciousness!

Is this jam suitable for canning and long-term storage?
Yes, this recipe can be canned using the water bath method to extend its shelf life. Be sure to follow safe canning practices to ensure your jam stays fresh and safe to eat.
Can I use frozen rhubarb?
Frozen rhubarb can be a convenient alternative and will work well for this jam. Just thaw and drain any excess water before cooking to avoid a watery jam.
How floral will the lavender flavor be?
The lavender adds a subtle, delicate floral note that complements the rhubarb beautifully without overpowering it. If you’re new to lavender in cooking, this balance keeps the jam approachable and delightful.
