Green gram, whole (pesalu)
Part used: seed
Small olive-green dried beans, the whole seed of the mung plant with its skin on. Mild, slightly grassy, and quick to soak. This is the pesarattu bean: soaked six hours and ground with ginger and chilli, it makes a green, savoury dosa with no fermentation. Whole pesalu are also sprouted (molakalu) and cooked into a light curry, or boiled with jaggery for a sweet. The split, skinned form (pesara pappu) is a different ingredient.
Storage
Airtight tin in a dry cupboard, up to a year. A dried red chilli or a few neem leaves in the tin keep weevils out. Old beans take longer to soak and grind gritty; buy from a shop with turnover.
Substitutes
For pesarattu there is no substitute — the green skin is the dish. For sprouts, whole moth bean or whole masoor behave similarly.
Benefits
- Traditional use· 3 sources
Green gram is traditionally regarded as the lightest pulse to digest — the one for the sick, the old and the convalescent.
The Charaka Samhita (Sutrasthana 27, Annapanavidhi) names mudga — green gram — the best of the pulses: astringent and sweet, dry, cooling, and "light". That single word laghu is why every Telugu grandmother gives pesara pappu kichidi or thin pesara pappu charu to someone recovering from fever, and why pesarattu is a breakfast and not a heavy dinner. It is a living tradition across India, not a Telugu quirk.
What research adds is background, not proof: the 2019 Nutrients review by Hou et al. summarises mung bean's protein, polyphenols and polysaccharides and a range of laboratory and animal findings. No human trial has compared how easily mung bean digests against other pulses. The measured facts are that it is high in protein (22.5 g/100 g) and fibre (17 g/100 g) and one of the fastest-cooking pulses. The "lightness" is tradition, and we label it so.
