Mustard oil. This is a major component of Bengali cookery. One of the defining flavours of Bengali cuisine has traditionally been mustard oil. Siddharth Dasgupta provides fascinating information.

Custard apple or sitaphal. A fruit with a knobbly green and black skin and creamy white flesh inside. It has large black seeds. More commonly wheat flour.
Sapodilla. A fruit which can be round or oval. Its thin skin is slightly rough and the flesh is dull, beige to terra cotta in colour and slightly granular with flat black seeds.

This can be dispelled by eating something fatty or wiping the lips with butter. One variety provides the gum for chewing gum.
