Buchanania cochinchinensis (syn. Buchanania lanzan) is a deciduous tree which produces seeds that are edible to humans. It is native to the Indian Subcontinent, Southeast Asia, and adjacent parts of China. It is known as chironji (or charoli). These almond-flavoured seeds are used as a cooking spice primarily in India. Buchanania cochinchinensis is cultivated across India, primarily in the northwest. After the hard shell is cracked, the stubby seed within is as soft as a pine nut.
The charoli seed is lentil-sized, is slightly flattened and has an almond-like flavour. Though they can be eaten and used raw they are often toasted or roasted before use, as this intensifies the flavour.
They are commonly used in sweets in India. They are also ground into powders for thickening savory sauces and flavoring batters, and stewed into rich, meaty kormas. Charoli seeds are used in the Ayurveda and Unani systems of medicine.
