Jalebi Recipe: Crisp Syrup-Soaked Spirals From an Overnight Fermented Batter

Master the art of making authentic jalebi — India’s iconic crispy, syrupy fermented sweet. This complete guide covers overnight batter fermentation, one-string sugar syrup technique, the art of the spiral, troubleshooting, and traditional serving traditions.

At a glance

Jalebi are spirals of fermented wheat batter, deep-fried at about 175–180°C and soaked briefly in saffron-cardamom sugar syrup. The batter is left overnight (12–24 hours at 25–30°C) to ferment; a metagenomic study found lactic acid bacteria, acetic acid bacteria and yeasts doing the work. Frying kills the microbes, so jalebi is a treat, not a probiotic food.

  • Batter of maida (refined wheat flour), often with yogurt, fermented overnight at 25–30°C.
  • Fermented jalebi batter holds lactic acid bacteria, acetic acid bacteria and yeasts.
  • Fry at about 175–180°C; soak in one-string syrup for 30–60 seconds.
  • Related sweets: zulabiya/zalabiya, Bengali jilapi, and urad-dal imarti.
  • Fried and syrup-soaked, with no live cultures.

Jalebi are bright orange-gold spirals of batter, deep-fried until crisp and soaked in saffron-cardamom sugar syrup – a festival, wedding and breakfast sweet across India and Pakistan, often eaten hot with milk or rabri. The batter is traditionally left overnight to ferment, which gives jalebi its light, slightly chewy inside and a faint sourness that balances the syrup. Similar fried, syrup-soaked sweets go by zulabiya or zalabiya in the Middle East; Bengal’s jilapi is a close cousin, and imarti is made from a urad-dal batter.

What Ferments the Batter

The first metagenomic study of naturally fermented jalebi batter, from India, found bacteria making up about 92% of the microbes. They included lactic acid bacteria – notably Lapidilactobacillus dextrinicus, Enterococcus hirae and Pediococcus stilesii – along with acetic acid bacteria (Acetobacter, Gluconobacter) and yeasts such as Pichia kudriavzevii and Wickerhamomyces anomalus. Several of these weren’t found in wheat sourdough, so jalebi batter has its own community (Shangpliang & Tamang, 2023). Together they produce the gas that lightens the batter and the acids that give it its tang. A spoonful of yogurt or a pinch of yeast helps it get going in a cool kitchen.

The Three Things That Matter

  • Batter: smooth, thick enough to pipe a thin rope that holds its shape, and visibly bubbly after fermenting.
  • Oil: about 175–180°C. Too cool and jalebi soak up oil; too hot and they brown before crisping.
  • Syrup: one-string consistency, warm when the hot jalebi go in, and a short soak (30–60 seconds) so they stay crisp. A few drops of lemon juice stop the syrup crystallizing.

Is Jalebi Healthy?

No more than any other fried, sugar-soaked sweet – enjoy it as a treat. Frying kills the batter’s microbes, so jalebi contains no live cultures; fermentation’s role here is texture and flavor. For fermented batters that become everyday food, see South India’s idli and dosa, or wheat sourdough.

Recipe: Jalebi With Overnight Batter

Makes
About 20 jalebi
Hands-on
45 min
Fermentation
12–24 hours at 25–30°C (8–12 with yeast)
Temperature
25–30°C (77–86°F) for the batter
Difficulty
Moderate

Equipment

  • Bowl and whisk
  • Squeeze bottle or piping bag with a small hole
  • Wide pan for frying
  • Thermometer
  • Saucepan for syrup

Ingredients

  • 125 g (1 cup) maida (plain flour)
  • 1 tbsp plain yogurt
  • ¼ tsp dry yeast (optional, for cool kitchens)
  • Pinch turmeric or saffron (for color)
  • About 180 ml (¾ cup) warm water
  • 200 g (1 cup) sugar (for the syrup)
  • 120 ml (½ cup) water (for the syrup)
  • Pinch + 4 saffron and crushed cardamom pods (plus 1 tsp lemon juice)
  • For frying ghee or neutral oil

Method

  1. Whisk the flour, yogurt, yeast (if using), turmeric and warm water into a smooth, thick batter. Cover and leave at 25–30°C for 12–24 hours (8–12 with yeast) until bubbly and slightly sour.
  2. Make the syrup: simmer the sugar, water, saffron and cardamom until it reaches one-string consistency; add the lemon juice and keep it warm.
  3. Beat the batter briefly and fill the squeeze bottle.
  4. Heat the oil to 175–180°C. Pipe spirals directly into the oil, a few at a time.
  5. Fry 1–2 minutes per side until crisp and golden, lift out, drain a moment, and dip in the warm syrup for 30–60 seconds.
  6. Serve hot. Discard batter that smells putrid rather than pleasantly sour.

Frequently asked questions

Is jalebi batter fermented?

Traditionally yes – the batter is left overnight and naturally fermented by lactic acid bacteria, acetic acid bacteria and yeasts, which lighten it and add tang.

Why are my jalebi soggy?

The oil was too cool, the syrup too thin, or they soaked too long. Fry at 175–180°C, use one-string syrup, and soak for under a minute.

Can I make jalebi without fermenting?

Instant versions use baking powder or soda and a short rest; they're quicker but lack the fermented tang and chew.

What's the difference between jalebi and imarti?

Jalebi is made from a fermented wheat batter in loose spirals; imarti is made from urad-dal batter piped into flower shapes.

Is jalebi probiotic?

No. The batter is fermented, but frying kills the microbes.

How long does jalebi keep?

It's best fresh and hot; it softens within hours. Leftover batter keeps a day in the fridge.
