Step-by-Step Instructions
Step 1: Prepare the Fruit
Start by washing the strawberries and rhubarb. Hull the strawberries (remove the green tops) and slice them into quarters. Chop the rhubarb into 1-inch pieces. These fruits will combine beautifully in your jam.
Step 2: Mix the Ingredients
In a large pot, combine the sliced strawberries and chopped rhubarb. Add the granulated sugar, lemon juice, and vanilla extract if using. Stir to coat the fruit evenly in the sugar and let it sit for about 10–15 minutes to release the juices.
Step 3: Cook the Jam
Turn the heat to medium-high and bring the mixture to a boil, stirring frequently. Once it starts boiling, add the fruit pectin and continue stirring. Cook for about 10-15 minutes, or until the mixture reaches a rolling boil and thickens. You can test the consistency by placing a spoonful on a cold plate, then running your finger through it; if it holds its shape, it’s ready.
Step 4: Jar the Jam
Once the jam has thickened, remove it from heat. Carefully pour it into sterilized jars, leaving about 1/4 inch of headspace at the top. Wipe the rims of the jars with a clean cloth to remove any residue that might prevent a proper seal.
Step 5: Seal the Jars
Place sterilized lids on the jars and screw on the bands until they’re fingertip-tight. You can process the jars in a boiling water bath for 10 minutes for longer shelf life, although this step is optional for immediate consumption.
Step 6: Cool and Store
Let the jars cool completely on a clean towel or rack. Once cooled, check that the lids have sealed properly (they should not flex when pressed). Store sealed jars in a cool, dark place or in the refrigerator for short-term use. Opened jars can be stored in the fridge for up to 3 weeks.
