Bold berry flavor, no pectin required, and perfect clarity in every spoonful.
Ingredients for Raspberry Jam
- 4 cups (about 500g) fresh raspberries – ripe yet firm (no mush).
- 3 cups (600g) granulated sugar – sweetness, preservation, and gel structure.
- 2 Tbsp fresh lemon juice – acidity for balance & natural pectin activation.
- Optional: ¼ tsp butter (reduces foam), pinch of salt (enhances fruit flavor).
No extra pectin—your raspberries and lemon juice handle the gel. Invest in fresh fruit, buy local, or use frozen in a pinch.
Seasonal Spotlight: Raspberries
Raspberries are nature’s quick-release flavor bombs—sweet, tart, and delicate. They’re high in pectin and acid, making them ideal jam candidates without needing chemical pectin. Handle them gently: that velvety juice is fragile, and crushing or over-stirring destroys structure. Warm climates and short windows mean raspberries stop being awesome fast—preserve them now or regret it later.
How to Make This Recipe
Step 1: Prepare the fruit
Rinse berries gently in a colander, pat dry. No soaking—that waters down flavor. Inspect for mushy or green berries, discard those. Gentle prep keeps your final jam clear and vibrant.
Step 2: Macerate (optional—but powerful)
Place raspberries, sugar, salt, and lemon juice in a heavy-bottomed pot. Gently stir, cover, and let sit 20–30 minutes until juices appear. This draws liquid, starts dissolving sugar, and builds flavor before heat touches it.
Step 3: Simmer to Gel
Heat over medium, stir slowly to dissolve sugar. Once bubbling, lower to gentle simmer. Cook 15–20 minutes, stirring every few minutes. The foam will rise—skim occasionally or add butter to reduce foam automatically.
Step 4: Gel Test
Use the chilled plate method: spoon jam onto a cold plate, wait 5 seconds, then push with your finger—if it wrinkles, it’s set. Alternatively, boil to 220°F. Raspberries cook quickly; watch so you don’t cook out flavor.
Step 5: Jar It
Sterilize jars and lids. Fill with hot jam, leaving ¼″ headspace. Wipe the rim, apply lid snugly but not overtightened.
Canning Raspberry Jam
For shelf-stable jam:
- Submerge filled jars in boiling water bath with rack.
- Process for 10 minutes (start timer when water returns to boil).
- Remove jars, let cool undisturbed 12–24 hrs.
- Test seal: lids should stay down when pressed.
- Store in a cool, dark pantry. Use within 1 year.
For fridge-only: seal the jars and store once cooled. Consume within 3 months.
FAQ
Can I use frozen raspberries?
Yes. Thaw and drain excess liquid first. Macerate slightly longer, then follow the simmer process. Texture may be looser.
Can I use less sugar?
Yes, but sugar is critical for texture and preservation. Reducing to 2 cups affects set—switch to pectin if using low sugar. Sugar substitutes like stevia or erythritol don’t gel well; avoid them unless using low-sugar commercial pectin.
How long does raspberry jam last?
- Fridge only: ~3 months
- Canned shelf-stable: up to 1 year
- Opened: Use within a month
- Freezer: Lasts up to 1 year
My jam didn’t set—what now?
Return to simmer, cook 5 more minutes, then re-test. If still loose, add 1 tsp lemon juice or 1 tsp powdered pectin, reheat to gel stage again.
My jam is too firm?
You overcooked it. Gently stir in a tablespoon or two of cold water over low heat, then cool. Retest clarity and texture.
