Mahlab Substitutes: Matching the Bitter-Almond, Vanilla-Like Kernel

Out of mahlab? Reach for almond extract, with a little vanilla alongside it. Nothing else tastes quite like this kernel from inside the mahaleb cherry’s stone, but two notes in its flavor give you something to aim for: bitter almond and a soft, vanilla-like warmth. It goes almost entirely into sweet breads and pastries like Greek tsoureki, Armenian chorak and Levantine ma’amoul. And if it’s a small part of a strongly flavored recipe, you can just leave it out.

Quick answer

How the ratios on this page are labeled

• Computed: based on a measurable physical relationship.
• Attributed: a named source publishes this ratio. We quote it as theirs.
• Disputed: named sources give different answers to the same swap. You get each one, side by side.
• Method: our starting point, based on how the two compare. Taste and adjust.

What you are trying to replace

Cooks describe mahlab in similar terms. Maureen Abood calls its flavor almond, earthy and incredibly gentle.¹ Eleanor Ford says it adds a sweet, almondy complexity to baking that sits gently in the background.² Curio Spice compares it to bitter almond and cherry.³ Katzer, tasting the raw kernel, finds it bitter and aromatic, with a subtle tonka-bean flavor that comes through after some chewing.⁴

Two groups of compounds match those descriptions:

• Benzaldehyde, the bitter-almond note. In a 2021 study of mahlab seeds, benzaldehyde was the most abundant aldehyde, and the authors say it accounts for the characteristic bitter-almond smell. Roasting lowered it.⁵
• Coumarins, the vanilla-like note. Katzer reports coumarin, dihydrocoumarin and herniarin in the kernels and calls coumarins “in all probability” the main flavor compounds.⁴ Coumarin is known for a pleasant, vanilla-like smell.⁶

So the closest substitutes bring a bitter-almond aroma and a soft vanilla warmth.

If mahlab is the bitter-almond perfume in a sweet bread or cookie

1. Almond extract

Almond extract is the closest match for the bitter-almond note that the 2021 study ties to benzaldehyde in mahlab.⁵ Read the label, because some extracts list bitter almond oil. Under US rules, bitter almond oil is allowed as a flavoring only when it’s free from prussic acid, and it can come from almond, apricot or peach kernels.⁷ What extract won’t give you is mahlab’s earthiness, its bitterness, or the texture of a ground kernel in the crumb.

Ratio (Method): Start with about 1/8 teaspoon pure almond extract per teaspoon of ground mahlab, added with the wet ingredients. Extract is concentrated and you can’t really taste a raw yeast dough, so stay low the first time and adjust on the next batch.

2. Almond extract plus vanilla

Vanilla points you toward the coumarin side of mahlab’s flavor, though not chemically. We found no source comparing vanilla’s aroma compounds with mahlab’s.

Ratio (Method): Use the almond extract above plus about 1/4 teaspoon vanilla extract per teaspoon of mahlab.

Why not tonka beans?

Katzer compares mahlab’s aftertaste to tonka beans,⁴ and US rules note that coumarin occurs naturally in tonka beans. But in the United States, food with added coumarin, alone or as part of tonka beans or tonka extract, is deemed adulterated.⁸ So they’re not a legal option in US cooking.

Why not bitter almonds?

Some cooks suggest raw bitter almonds. Food Standards Scotland advises against eating raw bitter almonds because they can contain high levels of cyanide, and notes they’re normally used only after further processing.⁹ You’ll often read that the FDA bans both the bitter almond kernel and the tree. We found no source for that. What US rules do say is that bitter almond oil is allowed as a flavoring only when it’s free from prussic acid.⁷ Almond extract is the safer way to get the same note.

Spices that are often suggested but don’t match well

Anise, star anise, fennel and cardamom show up on mahlab substitute lists. None of the sources on mahlab’s flavor mentions an anise or licorice note.⁴⁵¹²³ You’ll get a nice sweet bread, but it’ll taste of anise or cardamom, not mahlab.

Ratio (Method): If you use one, start with a small pinch, about 1/4 teaspoon ground spice per teaspoon of mahlab. Don’t combine it with almond extract unless you like both flavors together.

If mahlab is a small part of a strongly flavored recipe

Ratio (Method): If a recipe uses mahlab alongside stronger flavors, you can just leave it out. Where mahlab is the main spice, expect a noticeable difference.

A note on coumarin

Mahlab itself contains coumarin. One 2012 analysis measured 0.87 mg of coumarin per gram of fresh kernel,⁶ and EFSA’s tolerable daily intake is 0.1 mg of coumarin per kg of body weight.¹⁰ By our math, a 60 kg adult would hit that intake with about 7 g of kernels at that coumarin content every day. That’s far more than recipes use, and the figure comes from one study’s samples. We don’t know the coumarin content of other lots. The 2021 study notes that coumarins have been linked to liver damage and carcinogenic effects in experimental animals.⁵

Buying and keeping mahlab, if you find it

Katzer says to buy whole kernels, because the high fat content makes the powder spoil quickly.⁴ Abood keeps mahleb in the freezer,¹ and Curio Spice says to keep it in the fridge and grind right before use.³

What isn’t known

• Coumarin content was measured in one study’s samples. We didn’t find a survey of retail mahlab.
