Tej patta vs Bay leaf
The short answer
Two leaves sold under one English word, from different genera. Bay is Laurus nobilis, the Mediterranean laurel; tej patta is Cinnamomum tamala, a Himalayan cinnamon whose leaf smells of clove and cinnamon from eugenol and cinnamaldehyde. A South Asian recipe in English that asks for a bay leaf usually means tej patta, and the European leaf is one of the adulterants found in traded tej patta.
Side by side
| Tej patta | Bay leaf | |
|---|---|---|
| Botanical identity | Cinnamomum tamala (Buch.-Ham.) T.Nees & Eberm. | Laurus nobilis L. |
| Part used | leaf, bark | leaf |
| Origin | The wet tropical and subtropical forests of the Himalaya and its foothills, from India, Nepal and Bhutan to Bangladesh, Myanmar, Laos, Vietnam and China. | The Mediterranean basin, where it has been cultivated and gathered since antiquity. |
| Flavour notes | clove, cinnamon, warm, peppery | resinous, camphorous, herbal, faintly bitter |
| Heat | Scoville does not apply | Scoville does not apply |
| Flavour | Spicy and peppery, with the warmth of clove and cinnamon. | On its own, bay is bitter, medicinal and frankly unpleasant — chewing a leaf is the fastest way to conclude it does nothing good. In a long simmer it does something quite different: it lifts and lengthens a savoury background without contributing anything identifiable as itself. It is a spice that is noticed by its absence, which is a rare and useful property. |
| Aroma | Spicy, peppery and clove-and-cinnamon-like. The leaf oil’s main constituents are eugenol, methyl eugenol, cinnamaldehyde and cinnamyl acetate; in 28 leaf samples from the western Himalaya cinnamaldehyde made up 0.39–1.27 per cent of the leaf and was its largest fingerprint peak, while coumarin was absent from every sample from Himachal Pradesh and Jammu and Kashmir and reached 1.09 per cent in Uttarakhand. | Resinous and faintly camphorous when a leaf is torn — eucalyptus and pine with a warm background. Whole and undisturbed it smells of very little, which is part of why bay is so often assumed to be inert. |
Which should you buy?
Tej patta
Whole. The leaf is usually cooked whole and removed, and its aroma is a volatile oil that a powder loses.
Bay leaf
Buy whole leaf, in the smallest quantity sold, and replace it far sooner than you think. Bay is the spice most likely to be sitting in a cupboard doing nothing: it looks the same at six years as at six months, and because nobody can taste it directly nobody notices it has stopped working. Ground bay solves nothing — it fades faster and cannot be removed. If you have a garden, a bay tree is the one entry in this catalogue you can realistically grow, and fresh leaf is both better and free.
