Curry leaf and bay leaf
Two aromatic leaves that share the English word bay through a trade name, and that behave in opposite ways in a pan and in a cup. A recipe calling for Indian bay leaf usually means neither of them.

What is being compared
Why these get confused
Three different leaves attract the word bay in English — curry leaf, Laurus nobilis and tej patta. The taxonomic authority itself lists Indian bay as a common name for curry leaf, so the collision is recorded rather than merely colloquial.
Point by point
| Aspect | Curry leaf | Bay leaf |
|---|---|---|
| Plant | Bergera koenigii, in the citrus family, though nearly all trade and published work still calls it Murraya koenigii. | Laurus nobilis, in the laurel family and unrelated to the other two. |
| Where the name collides | Sold as Indian bay, which is also a name for tej patta, the leaf of Cinnamomum tamala. | The original bay. Turkey supplies most of the dried leaf traded worldwide. |
| Aroma | Citrus and something close to burnt sugar, strongest in the seconds after the leaf hits hot fat and gone within a day of drying. | Camphorous and slightly medicinal, and it survives drying almost completely. |
| In the cup | Faint and short-lived. Fresh leaves give a light citrus infusion; dried ones give very little. | Assertive and bitter on a long steep. A single leaf is usually too much for a mug. |
| Keeping | Poor. The whole point of curry leaf is freshness, and freezing keeps it better than drying. | Excellent. Dried bay holds its character for a year or more. |
The short answer
They are not substitutes in either direction. If a South Asian recipe says curry leaf, no bay leaf will do; if a European one says bay, curry leaf will vanish.
