Questions to ask about allergens before you order in
Ask these 4 key questions about allergens before ordering takeaway or delivery. Learn what good answers sound like and how to spot evasive restaurants.
You're ordering dinner for yourself and a friend. One of you has a shellfish allergy. You scan the menu online—plenty of options that don't list shellfish—but you're not sure if the kitchen uses the same chopping boards, shared utensils, or cooking oil. The menu silence on cross-contamination is making you hesitate. This is the moment to stop and ask.
Allergen questions feel awkward because they carry weight. A wrong answer, a miscommunication, or a kitchen that doesn't take your concern seriously can mean a hospital trip. Restaurants and cafés should take allergen queries as seriously as you do. Knowing what to ask, and how to interpret the answers you get, keeps you safe.
"Does this dish contain [allergen]?"
Start here. Be specific. If you're allergic to peanuts, ask about peanuts, not "nuts"—tree nuts and peanuts are different allergens, and a kitchen might stock both. A good answer names the ingredient directly: "No, we don't use peanuts in that dish." An evasive answer sounds like "It shouldn't have any" or "I don't think so." Those words—shouldn't, think—are red flags. You're looking for certainty, not guesses.
When you call or message on WhatsApp, speak to someone who can check the recipe or ask the chef. If they have to go away and come back with an answer, that's actually a good sign—they're verifying, not winging it. If they tell you to "just order it" or act annoyed by the question, hang up. Find another place.
"Do you prepare this dish near other allergens?"
This is about cross-contamination. A restaurant might not use sesame in a particular salad, but if they blend sesame paste in a mortar five minutes before, and don't wash it, tiny particles end up in that salad. Good kitchens have separate prep areas, colour-coded utensils, or washing protocols between allergen-free and allergen-containing dishes. A reassuring answer includes details: "We use a dedicated cutting board for allergen-free orders" or "We change our gloves and wash all surfaces."
Weak answers dodge the question: "It's fine" or "Don't worry." You need to know *how* they're being careful, not just that they say they are. If they can't explain their process, they probably don't have one.
"Can you prepare this without oil or equipment shared with [allergen]?"
Some allergies are so severe that even airborne particles or minute traces matter. If that's your situation, be direct about it upfront. Ask whether the kitchen can genuinely isolate your order—separate pan, separate oil, separate workspace. Some places can; some can't. A kitchen that says "We can't guarantee that level of separation" is being honest and protecting you. One that promises absolute safety without explaining how is either lying or doesn't understand the risk.
If the restaurant can't accommodate you, don't order. No menu item is worth anaphylaxis. Many restaurants on Strove note allergen protocols in their profile or will answer detailed questions over WhatsApp—use that to vet them before you commit.
"What's in the sauce, and where are the spice blends from?"
Hidden allergens live in sauces, stocks, and seasoning mixes. A "special sauce" might contain tree nuts, fish sauce, sesame, or soy. Shop-bought spice blends sometimes list only major allergens on the label, not every ingredient. A thoughtful kitchen keeps labels or ingredient lists on hand, or the chef can tell you what's in house-made blends. If they pull up a supplier's information sheet or tell you "I'll check the packet," they're being serious.
If the answer is vague—"It's a secret recipe" or "It's complicated"—push back. Allergy safety isn't about protecting trade secrets; it's about protecting your health. The right restaurant understands this.
When you've asked these questions and feel confident in the answers, you can order safely. The best takeaway places respond to allergen questions calmly and thoroughly, and they keep good notes so your order arrives prepared the way you need it. If you're building a list of reliable places for emergency nights, make allergen friendliness part of how you vet them.
Common questions
- What should I do if a restaurant can't answer my allergen question confidently?
- Don't order from them. A reliable kitchen either knows their ingredients and procedures or will take time to find out before confirming. If they're dismissive or uncertain, that's a sign they may not have proper allergen controls in place.
- Is it better to call or message about allergens?
- Either works, but messaging (WhatsApp, email) creates a record of what was discussed, which is helpful if something goes wrong. Phone calls let you ask follow-up questions in real time. Many people do both—message first to reach the right person, then call to speak with them directly.
- Should I mention my allergy severity when I ask?
- Yes. If you have a severe allergy that requires zero cross-contamination, say so upfront. This helps the kitchen decide whether they can actually help you safely, rather than promising something they can't deliver.
- What if the takeaway says they use 'nut-free' seasoning but don't have the label?
- Ask to see the packet or ingredient list before your order goes in, or ask them to call their supplier. A reputable place will do this without complaint. If they can't or won't verify, find somewhere else.
