Ingredients

  • Sweet ripe fruit (banana, papaya, mango, grape, melon, apple)1 part by weight
  • Jaggery / brown sugar1.2–1.3 parts by weight (summer); 1 part (winter)

How to make it

  1. Step 1

    Gather at least 3 fully ripe local fruits — picked or fallen. Do NOT wash.

  2. Step 2

    For every 1 kg of fruit weigh out 1.2–1.3 kg jaggery in summer, 1 kg in winter.

  3. Step 3

    Sun-dry the jar to disinfect it, then spread half the sugar on a chopping board.

  4. Step 4

    Dice fruit starting with the sweetest, smear with sugar, and pack into the jar quickly.

  5. Step 5

    Pour the remaining half of the sugar over the top.

  6. Step 6

    Stir 2–3 times with a wooden stick — fewer strokes in summer, more in winter.

  7. Step 7

    Cover with porous paper and tie. Ferment 4–5 days (summer) or 7–8 days (winter).

  8. Step 8

    Sprinkle more sugar over the top, then store cool and shaded.

What it is

FFJ is an artificial honey — a nutritional activation enzyme made just like FPJ, but from sweet ripe fruit instead of leaves. Sugar draws the juice out by osmosis while the wild yeast on the skins ferments it. The result revitalizes crops, livestock and humans, and re-energizes plants as they move from growing into fruiting.

On the Nutritive Cycle: FFJ spans the cross-over and reproductive stages. Less-ripe fruit (grape, papaya, mulberry, raspberry) is sour and rich in phosphoric acid for the flowering cross-over; fully-ripe fruit (apple, banana, mango, peach, grape) supplies the calcium demand of the fruiting stage.

When to use it

  • Cross-over period — less-ripe-fruit FFJ for the phosphoric-acid demand of flowering.
  • Reproductive growth — ripe-fruit FFJ for calcium as fruit sets.
  • After cross-over — apply diluted 1:1000 in water; also spray chicken housing, vegetables and orchards for disease protection.

Use grapes only for grapes and citrus only for citrus — their cold, sour character harms other crops.

Materials

  • Sweet ripe fruit — 1 part by weight (at least 3 fruits)
  • Jaggery — 1.2–1.3 parts in summer, 1 part in winter
  • Wide jar, wooden ladle, chopping board, porous paper

How to make it

  1. Ripe and unwashed. Use local fruit; add spinach root, wild yam, cucumber or radish if short on fruit.
  2. Sugar it by weight. More sugar in summer controls moisture; less is needed in cold winter.
  3. Dice and pack fast. Sweetest first, smear with half the sugar, then top with the rest.
  4. Stir gently 2–3 times, cover with porous paper, and ferment 4–8 days depending on season.
  5. Top with sugar and store. A little sugar on the surface is normal.

Signs it worked / troubleshooting

  • ✅ Good: tiny bubbles boiling fiercely at once = strong enzyme power.
  • ⚠️ Big bubbles popping slowly = weak enzyme → give it more time.
  • 🚫 Foul rot or slime = contaminated → discard and restart with more sugar.

How to store

Keep in a cool, shaded place with extra sugar sprinkled on top. Some surface sugar is normal and helps it keep.
