Apricot kernels sit in a glass jar of noyaux (homemade almond extract).

What is Noyaux?

Noyaux is the name for both the bits of stone fruit and the aromatic liqueur made from them. This liqueur has the sweet, intoxicating aroma that you'll also find in bitter almonds and almond extract. Because of its deep almond-like aroma, it makes an excellent homemade almond extract.

Noyaux is also traditionally made in France, where cooks use it to flavor ice creams, custards, and other desserts. It has an old-fashioned charm, like homemade herbal root beer or real brandied cherries.

How to Make Noyaux

To make noyaux at home, you'll need to follow three steps. First, you'll need to extract the kernels from apricot pits. Next, you'll need to let them soak at least three months. Lastly, you can decant the liqueur for easy storage. Alternatively, you can keep adding alcohol and apricot kernels for a perpetual supply.

Extracting the Kernels

Apricot stones cling furiously to their kernels. And extracting them takes patience, skill, and strength.

If you clean the stones well and let them dry until they turn brittle, you'll have an easier time extracting the kernels. I like to tuck the cleaned stones into a food dehydrator to dry them quicker.

Pounding them with a hammer until the tough stone cracks to reveal the soft, aromatic kernel works well.

Soaking the Kernels in Alcohol

Next, you'll want to soak the kernels in alcohol to make noyaux. Soaking over a period of several months allows enough time for you to extract all the aroma and flavor from the kernels.

Apricot Kernels and Safety

Many traditional almond-flavored liqueurs are made with stone fruit kernels and apricot pits. And noyaux, as well as Amaretto, are traditionally made with pits from stone fruit. Further, stone fruit pits themselves are a critical part of many traditional recipes for Italian amaretti as well as the Middle Eastern seasoning mahleb.

Noyaux is made in country kitchens throughout France. Moreover, cooks use the pits of stonefruits not only in extracts but also in pastries and as seasonings.

But there's something else you should consider: Apricot kernels, noyaux, and the pits of stone fruit contain plant poisons.

Apricot kernels, apple seeds, and cherry pits all contain small amounts of amygdalin, which is a precursor to cyanide. As a result, homemade noyaux will also contain amygdalin

But, as Paracelsus wrote, "The dose makes the poison."

And in the case of a homemade almond extract like this one, the dose is invariably tiny when you consider that you may use ¼ to ½ teaspoon to flavor an entire dish.

There's also a concept in toxicology called hormesis - that is a very, very small dose of something that is toxic in a larger amount may actually convey a beneficial effect (1). To that end, the use of apricot kernels has been popularized as an alternative cancer treatment, but there's really no evidence that supports its use (2, 3, 4).

Since stone fruit pits and extracts made from them are enjoyed in minute quantities throughout Europe and the Middle East, I'm inclined to use tiny amounts in my own kitchen.

Authorities estimate that eating up to 2 apricot kernels daily is safe (5). Assuming all of the amygdalin in this noyaux recipe. Each teaspoon of homemade almond extract would contain the equivalent of about ⅓ of an apricot kernel. Considering that's further spread out over an entire recipe that may feed six or more.

So where does that leave us in terms of safety? Use small amounts only, and keep it away from children (as well as anyone else who might mistakenly drink it). Or simply appreciate it as a novel recipe.

30 apricot kernels
2 cups light rum

Instructions

Place the apricot kernels in a quart-sized jar, and cover them with light rum. Seal the jar, and allow kernels to soak in the rum at room temperature for at least 3 months before straining.
As you remove the extract, you can replace it with more rum or add more apricot kernels, thus keeping a constant supply of noyaux.
