Sesame Allergy in Canada: Tahini, Oil and Hidden Seeds

Sesame allergy in Canada is easier to manage once you know sesame's other names. Health Canada's sesame page lists tahini, tahina, gingelly oil, til and benne among them, and says sesame is a priority food allergen. On a menu those words can appear in a recipe or a spice blend where the word sesame itself never does, so a kitchen's description may need translating.

What does a sesame allergy in Canada involve at a restaurant?

Sesame is one of eleven priority allergens on Health Canada's list, which also names peanuts, tree nuts, milk, eggs, fish, crustaceans and molluscs, soy, wheat and triticale, mustard and sulphites. The Mosey app offers sesame among the first choices a Canadian place sees when it lists a dish. The Health Canada page does not describe restaurant rules, so a diner's best tool is a plain question that uses the right words.

Sesame is usually small in quantity and large in effect, which is the opposite of how most diners think about an allergen. We tend to picture the main ingredient, the fish fillet or the peanut sauce, so a seed or a paste that arrives as a garnish slips past the question. Cooks make the same assumption in reverse and may not think a topping is worth mentioning. A scattering of seeds, a spoonful of paste or a splash of oil is easy for a cook to leave out of a description, and easy for a menu to omit.

What are the other names for sesame?

Health Canada lists the names to look for: tahini (sesame paste) and tahina, gingelly and gingelly oil, sesamol and sesamolina, Sesamum indicum, sim sim, til, and benne, benne seed and benniseed. It adds that on a packaged-food label some of these names may be used only if the label also says sesame. A menu has no such rule on the page, so a recipe may call something til in a lentil dish or gingelly oil in a South Indian dish, or benne in a Southern recipe, and a diner may never hear the word sesame at all.

Use the names as questions. Ask whether a dish contains sesame in any form, including tahini, gingelly oil or til, and ask the same of a spice mix.

It helps to carry the short list on your phone. A server who hears "sesame" may check the obvious seeds on the bun, while a server who hears "tahini, gingelly oil or til" will think about the paste, the oil and the spice tin. Say the allergy first, then the names, and keep the tone friendly: kitchens answer better to a clear, calm request than to a long list recited at speed. If you eat with the same group often, tell them the names once so they can speak up at the table.

Where do dips and dressings carry sesame?

Health Canada lists dips and spreads, dressings, sauces, soups, and herbs and spices among the foods that contain or often contain it. A garlicky white sauce on a wrap, a hummus-style dip, a vinaigrette, a noodle sauce and a spice sprinkle on flatbread are all places to ask. The page also names sesame salt, called gomasio, among the foods that contain it, plus vegetable pâtés and snack bars. If a dish arrives topped with a dark crumbly sprinkle, a pale cream drizzle or a seeded crust you did not expect, ask before the first bite, not after.

Do vegetarian burgers and tempeh count?

Health Canada's list includes tempeh and vegetarian burgers as foods that contain or often contain sesame, which is worth knowing because they are ordered by diners who assume a plant-based plate has a short ingredient list. If a menu offers a plant-based patty, a tempeh bowl or a snack bar, ask about its ingredients. Health Canada also notes that vegetable oil may contain sesame oil, so a general fry oil or dressing base can be a question too.

What should you ask about sesame oil?

The two oils are the same thing under different names, and Health Canada counts it among foods that contain or often contain sesame. Ask whether a stir-fry, a noodle dish, a marinade or a dressing is finished with it, and whether the kitchen's cooking oil is a blend. Cooks use it in small amounts for aroma, which is exactly why it goes unmentioned. A noodle bowl, a dumpling dipping sauce, a poke-style dressing and a flatbread brushed before baking are all places where one drizzle changes the answer. If the answer is that "it's just a little", ask for the dish to be made another way. The general conversation for any allergen is in eating out with food allergies in Canada.

How does Mosey show sesame on a menu?

A place can tick a dish as Contains sesame or May contain sesame, and the dish filter called Hide dishes that list will hide dishes that list it. A dish with no entry stays visible, marked "Allergens not listed, ask the place", which is a reason to ask and never a sign that a dish is fine. The wording is explained in priority allergens on a Canadian menu.

Rate the dish, not only the place, and note the names you used and what the cook said. Tags are one diner's note about one visit, never a promise. A private list of places that answered clearly can be shared with friends. A place can fill in its allergens in its dashboard, and Mosey is free to list, with no hidden fees and affordable tools, which helps local kitchens spell out what goes in their food. There is more in the Canadian food guides.

Once you have a name list that works, get the Mosey app, rate your next dish and note which word the kitchen recognized.
