Ingredients

• 4 cups rhubarb, chopped into 1/2-inch pieces (about 1 pound)
• 3 cups fresh blackberries (or frozen, thawed)
• 4 cups granulated sugar
• 1/4 cup fresh lemon juice (about 1-2 lemons)
• 1 teaspoon grated lemon zest
• 1 packet powdered pectin (about 1.75 ounces)

Equipment

• Large heavy-bottomed saucepan or jam pot
• Wooden spoon or heat-resistant spatula
• Measuring cups and spoons
• Fine mesh strainer or food mill (optional, for smoother jam)
• Glass canning jars with lids (sterilized)
• Jar funnel (optional, but helpful)
• Large pot for water bath processing (if preserving)
• Jar lifter or tongs

Instructions

1. Prepare the fruit: Wash the rhubarb and blackberries thoroughly. Chop the rhubarb into 1/2-inch pieces and set aside.
2. Combine fruit and pectin: In a large saucepan, combine the rhubarb, blackberries, and powdered pectin. Stir well to incorporate.
3. Bring to a boil: Place the saucepan over medium-high heat and bring the fruit mixture to a full rolling boil, stirring frequently to prevent sticking.
4. Add sugar, lemon juice, and zest: Once boiling, add the sugar, lemon juice, and lemon zest. Stir continuously until the sugar dissolves completely.
5. Boil hard: Bring the mixture back to a full rolling boil and maintain for 1-2 minutes, stirring constantly. This step activates the pectin and helps the jam set.
6. Test the jam: Remove the pan from heat. To test for setting, place a small spoonful of jam on a cold plate and let it sit for one minute. If it wrinkles when pushed with a finger, the jam is ready. If not, boil for another minute and test again.
7. Skim foam: If there is any foam on the surface, skim it off with a spoon to ensure a clear finish.
8. Jar the jam: Using a funnel, carefully ladle the hot jam into sterilized jars, leaving about 1/4 inch of headspace at the top. Wipe the rims clean and seal with lids.
9. Process jars (optional): For long-term storage, process the jars in a boiling water bath for 10 minutes. Remove and let cool completely. You should hear the jars “pop” as they seal.
10. Store and enjoy: Store the sealed jars in a cool, dark place for up to one year. Refrigerate after opening and enjoy within a month.

Tips & Variations

“For a smoother jam, use a food mill or fine mesh strainer to remove seeds after cooking. If you prefer chunkier jam, simply mash gently with a potato masher before cooking.”

Adjust the sweetness to taste by reducing the sugar slightly if you prefer a tarter jam. Keep in mind this may affect the set and shelf life.

Try adding a teaspoon of ground ginger or cinnamon during cooking for a warm spice twist. For a lower-sugar option, experiment with natural sweeteners like honey or maple syrup, but note that this may change the texture and setting time.

Want a richer fruit flavor? Substitute half of the blackberries with blueberries or raspberries.
