Anise tastes like licorice, but with a bolder, more aromatic edge. It’s sweet, warm, and slightly herbal, with a flavor intense enough that a small amount goes a long way. If you’ve ever had black licorice candy, Italian biscotti, or a glass of ouzo, you’ve already encountered the signature taste of anise.
The Core Flavor Profile
The dominant note in anise is unmistakably licorice-like, but calling it “licorice flavored” sells it short. Anise has a natural sweetness that lingers as an aftertaste, along with earthy, herbal undertones that give it more complexity than straight licorice candy. When you chew an anise seed, the sweetness hits first, followed by a warm, aromatic intensity that fills your nose and mouth simultaneously. It’s a flavor you experience as much through smell as through taste.
Compared to fennel, which shares a similar licorice quality, anise is noticeably more potent. Biting into an anise seed delivers a sharper burst of flavor than biting into a fennel seed, which tends to be milder and gentler. Anise also carries a slight astringency, a subtle drying sensation, that fennel mostly lacks. That intensity is why recipes calling for anise seed typically use it sparingly.
Why It Tastes Like Licorice
The flavor compound responsible for that licorice taste is called anethole, and anise seeds are loaded with it. Depending on the variety and ripeness, anethole makes up roughly 66 to 93 percent of anise’s essential oil. It’s also the same compound found in fennel, star anise, and even actual licorice root, which is why all of these ingredients remind people of each other despite coming from completely different plants.
But anethole only tells part of the story. Anise contains secondary compounds that give it a character all its own. One contributes sweet, floral, almost vanilla-like notes. Another reinforces that distinctly “anisey” quality that’s hard to describe as anything other than itself. These background flavors are what make anise taste like anise rather than a generic licorice substitute.
How Anise Compares to Similar Flavors
People often lump anise, star anise, fennel, and licorice together, but they taste noticeably different once you try them side by side. All four share anethole as their dominant flavor compound at similar concentrations, yet each plant produces its own set of secondary compounds that push the flavor in a different direction.
- Anise seed tastes earthy and licorice-forward, with a sweet, herbal quality. It pairs naturally with baked goods and sweet dishes.
- Star anise is bolder, with woody, lemony, and slightly tea-like notes layered over the licorice base. It’s the one you’ll find in pho and Chinese five-spice powder.
- Fennel seed leans piney and slightly camphor-like, with a cooler, mintier edge. It’s the mildest of the three and works well in savory dishes like sausage and roasted vegetables.
- Licorice root is sweeter than all of them, thanks to a compound called glycyrrhizin that delivers an intensely concentrated sweetness. But as a root, it also carries a slight bitterness, sometimes described as metallic, along with deeper earthy notes.
These differences matter in cooking. America’s Test Kitchen has noted that anise seed, fennel seed, and star anise aren’t interchangeable in recipes because their secondary flavors push finished dishes in distinctly different directions. Swapping one for another will get you in the neighborhood, but the result won’t taste the same.
What It Feels Like in Your Mouth
Beyond flavor, anise produces a mild warming sensation as you eat it. The seeds themselves are small and crunchy, and chewing them releases their aromatic oils quickly. Some people detect a very faint cooling effect, similar to a whisper of menthol, though it’s subtle enough that most people register it as general “freshness” rather than an actual chill. The overall mouthfeel is warm and slightly drying, with an aroma that seems to travel up through the back of your throat into your sinuses.
That aromatic intensity is also why anise is so closely associated with spirits. Drinks like ouzo, pastis, absinthe, sambuca, and arak all rely on anise or anethole for their signature flavor. When you add water to these clear spirits and they turn cloudy, that’s the anethole coming out of solution, a visual reminder of just how much of that compound is packed into each sip.
How Cooking Changes the Flavor
Raw anise seeds deliver the sharpest, most pungent version of the flavor. Toasting the seeds in a dry pan mellows the licorice edge and brings out warmer, nuttier notes. Ground anise loses its punch faster than whole seeds because the essential oils evaporate once the seed coat is broken, so freshly ground anise will always taste stronger than pre-ground powder that’s been sitting in your spice rack.
In baked goods like biscotti, pizzelle, and springerle, the sweetness of anise comes to the foreground while the sharper herbal notes soften. In savory applications like spice rubs, stews, and braised meats, anise adds a background warmth and complexity without making the dish taste sweet. Both the seeds and the leaves of the anise plant carry the same essential flavor, though the leaves are milder and work better as a fresh garnish.
If you’re unsure whether you like anise, the simplest test is a piece of black licorice candy. In the United States, most black licorice is actually flavored with anise or star anise extract rather than real licorice root. If you enjoy that candy, you’ll almost certainly enjoy cooking with anise. If you find it overwhelming, start with fennel seed instead, which delivers a gentler version of the same family of flavors.
