The best-ever homemade blueberry jam
🫐✨ Homemade Blueberry Jam — Thick, Glossy & Bursting with Flavor
A naturally thickened blueberry jam made with real fruit, sugar, and a touch of green apple for perfect texture — no commercial pectin needed.

- 1 kg blueberries (fresh or thawed)
- 700 g sugar (up to 800 g for sweeter jam)
- ½ green apple, grated (with peel)
- 1 tsp grated lemon zest (optional)
- 1 tsp lemon juice (optional)
How to Make
Step 1: Macerate the Blueberries
- Layer blueberries and sugar in a large pot.
- Rest 2–3 hours or overnight in the refrigerator.
- The fruit will release natural juices.
Step 2: Add Apple & Lemon
- Add grated green apple.
- Add lemon juice and zest if using.
- Stir gently.
Step 3: Boil
- Bring to a gentle boil over medium heat.
- Skim off foam.
Step 4: Cook in Stages
- Cook 10 minutes, then remove from heat.
- Cool completely.
- Repeat 2–3 times for better texture.
Step 5: Test & Finish
- Test on a cold plate.
- Boil 3–4 minutes more if needed.
Step 6: Jar the Jam
- Pour into clean, preheated jars.
- Seal and invert for 24 hours.
Tips
- Green apples are rich in natural pectin.
- Pectin + sugar + acid creates natural gel.
- Lemon improves shelf life and color.
- Without lemon, flavor is softer and fruitier.
