Sesame became the ninth major food allergen recognized by the FDA when the FASTER Act took effect in January 2023. But despite its official status, sesame remains one of the sneakiest allergens to avoid — and tahini is the number one reason why.
What Is Tahini, Exactly?
Tahini is a paste made from ground, toasted sesame seeds. Think of it as the sesame equivalent of peanut butter. It has a rich, nutty flavor and a creamy texture that makes it incredibly versatile in cooking.
On its own, tahini is easy enough to spot on an ingredient label. The problem is that tahini hides inside dozens of popular foods where most people wouldn't think to look.
Where Tahini Hides
Here are some of the most common foods that contain tahini — and therefore sesame:
- Hummus — Tahini is a core ingredient in traditional hummus, not just a garnish. Most store-bought and restaurant hummus contains a significant amount.
- Baba ganoush — This roasted eggplant dip almost always includes tahini.
- Halva — A dense, sweet confection made primarily from tahini and sugar.
- Falafel sauces — The white drizzle on your falafel wrap is very often tahini-based.
- Salad dressings — Many Middle Eastern, Mediterranean, and even some Asian-style dressings use tahini as a base.
- Energy bars and health foods — Tahini appears in many "natural" snack bars as a binding agent or flavor component.
- Sushi rolls — Some specialty rolls include sesame paste or tahini in sauces.
- Noodle dishes — Sesame noodles and some Thai-inspired peanut sauces may include tahini.
Why It's So Easy to Miss
Unlike peanuts or milk, sesame hasn't been on most people's radar for very long. Many restaurants and food manufacturers are still catching up with labeling practices. Here's what makes it tricky:
-
Vague labels. Before 2023, sesame could hide under terms like "natural flavors" or "spices" on ingredient lists. While labeling has improved, older products or imported foods may still use vague terminology.
-
Cross-contact in bakeries. Sesame seeds are everywhere in bakeries — on buns, bagels, and breads. Even if your item doesn't contain sesame, it may have been prepared on the same surface or in the same oven.
-
Restaurant assumptions. Many cooks use tahini as a staple ingredient without thinking of it as an allergen. It may not be listed on the menu description, especially in Mediterranean, Middle Eastern, or Asian cuisines where it's considered a basic pantry item.
-
It doesn't taste "sesame-y." When tahini is blended into a dressing or dip, its flavor often disappears into the background. You can't rely on taste to detect it.
How to Protect Yourself
If you or someone you care about has a sesame allergy, here are practical steps:
- Always ask specifically about tahini and sesame when dining out — don't just ask about "allergens" in general, since staff may not think of sesame automatically.
- Read every label, every time. Manufacturers change recipes. A product that was safe last month may not be safe today.
- Be extra cautious with Mediterranean and Middle Eastern food. These cuisines use tahini as a foundational ingredient.
- Use ForkSure! Point your camera at the food and let the app flag potential sesame exposure before you take a bite.
The Bottom Line
Tahini is delicious, nutritious, and increasingly popular — which is exactly what makes it dangerous for sesame-allergic individuals. It shows up in unexpected places, it blends in seamlessly, and many people (including restaurant staff) don't realize it's a concentrated sesame product.
Awareness is your best defense. Now that you know where tahini hides, you'll be much better equipped to ask the right questions and avoid accidental exposure.
