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

AspectCurry leafBay leaf
PlantBergera 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 collidesSold 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.
AromaCitrus 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 cupFaint 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.
KeepingPoor. 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.
