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.
