Lowbush Blueberry Jelly
A bright, clear wild-blueberry jelly. Simmer berries to extract juice, strain, then cook with sugar and lemon to the gel point. After jarring, turn the leftover pressed pulp into chewy fruit leather or a quick marmalade—nothing wasted.

Cuisine preserving, wild fruit
Large pot
Wide pot or canner for the water bath
Fine sieve or cheesecloth
Heatproof bowl or measuring jug
Ladle and canning funnel
Kitchen thermometer or cold-plate for gel test
Sterilized jars with lids
Jar lifter or tongs
- 4 cups lowbush blueberries Vaccinium angustifolium, washed
- 1 cup water
- 3 cups sugar
- 1 tablespoon lemon juice
- Optional pectin: 1–2 teaspoons apple-pectin powder or liquid pectin as per label (only if needed)
Prepare the berries: Wash well and lightly crush to help release juice.
Extract juice: Combine berries and water in a large pot. Bring to a boil, then simmer gently for ~10 minutes until soft.
Strain: Pour through a cheesecloth-lined sieve. For the clearest jelly, let it drip without pressing; for more yield, press lightly.
Make the jelly base: Measure the collected juice back into a clean pot. Add sugar and lemon juice; stir to dissolve.
Add pectin (optional): If using pectin, add now per manufacturer’s directions.
Cook to gel point: Boil briskly, stirring often, until the gel test passes or the thermometer reads about 105 °C / 220 °F. Skim any foam.
Fill the jars: Ladle hot jelly into hot, sterilized jars, leaving 5–7 mm headspace. Wipe rims and apply lids.
Water-bath process: Submerge and process 10 minutes at a gentle boil (add 5 minutes above ~300 m / 1,000 ft). Remove to a towel, cool undisturbed, and check seals.
- Flavor: Lowbush blueberries are naturally aromatic; lemon brightens and balances.
- Pectin: Wild berries vary—add pectin only if your gel test is slow.
- Clarity vs. yield: No pressing → brightest, clearest jelly. Light pressing → more volume and deeper color.
- Storage: Store sealed jars cool and dark for 12–18 months. Refrigerate after opening and use within 3–4 weeks.
- Safety: Work clean and sterilize equipment. Discard any jar that fails to seal or shows gas, off-odors, or mold.

Using the Pressed Fruit (after Jelly): Fruit Leather & Marmalade
Why
The strained pulp still has flavor, color, and fiber. Turn it into snacks or a spread.
Equipment (add-ons)
- For both: mixing bowl, spatula, measuring spoons/cups
- Fruit Leather: dehydrator or oven, baking sheet, parchment/silicone mat, knife/scissors
- Marmalade: saucepan, wooden spoon, immersion blender (optional), fine sieve (optional), clean jars/lids, funnel
Fruit Leather (per ~2 cups / 480 ml pulp)
Ingredients
- 2 cups pressed blueberry pulp (well drained)
- 2–4 tbsp sugar or maple syrup (optional)
- 1–2 tsp lemon juice (optional)
Steps
- Preheat dehydrator to 50 °C / 122 °F (or oven to its lowest setting, ideally 50–60 °C / 120–140 °F; prop the door slightly open).
- Mix pulp with sweetener/lemon to taste.
- Spread 2–3 mm thick on a lined tray.
- Dry 4–8 hours until leathery, not sticky; rotate trays if needed.
- Peel off, cut into strips, roll, and cool before storing airtight (up to 1–2 months; refrigerate in humid climates).
Quick Marmalade (ratio by volume/weight)
Ingredients
- 2 parts pressed blueberry pulp
- 1 part water (add a little more only if very thick)
- ½–1 part sugar (start low; adjust)
- Optional: 1–2 tsp lemon juice; tiny pinch cinnamon or vanilla
Steps
- Simmer pulp, water, and sugar 15–25 minutes, stirring often, until thick and glossy.
- Blend briefly for smoothness (optional). For extra fine, push through a sieve.
- Jar hot into clean jars. Cool, then refrigerate and use within 2–3 weeks.
- Pantry option: Water-bath process 10 minutes (add 5 minutes above ~300 m / 1,000 ft). Store cool/dark; refrigerate after opening.
Tips
- Yield guide: 2 cups pulp → one dehydrator sheet of leather or ~1½–2 cups marmalade.
- Texture control: Leather too soft? Dry longer/thinner. Marmalade too loose? Simmer a few more minutes; too thick? Stir in a splash of hot water.
- Flavor ideas: Add citrus zest, a dash of maple, or blend pulps (e.g., bunchberry + blueberry) for color and taste.
- Safety: Use same-day fresh pulp. If you notice fermentation or off odors before reuse, discard.
