How it works

  1. 1Sugar = fruit × 50% (safe range 40-60%) = 500 g
  2. 2Lemon juice = fruit × 30 ml/kg = 30 ml
  3. 3Yield ≈ 65% of fruit + sugar (cooked to 105°C) ≈ 975 g
  4. 4Jars = ⌈975 ÷ 250⌉ = 4
Pick firm, 70-80% ripe fruit — overripe turns sour; add apple for pectin with low-pectin berries; add sugar in two batches, lemon juice last; stir and skim until 105°C; fill hot, leave 1 cm headspace, invert 30 min to seal; refrigerate after opening and use within a month; discard at any sign of mould or fermentation.
