Restaurant Dietary Quick-Reference Staff Training Guide
Understanding the Three Different Conditions
This is one of the most misunderstood dietary categories. Three distinct conditions require gluten-free food — and they are not the same.
Condition | What It Is | Severity | Service Implications |
Coeliac Disease | Autoimmune disorder — gluten triggers the immune system to damage the small intestine | Very serious — even trace amounts (20ppm) cause harm | Requires strict cross-contamination prevention. Treat it as a medical necessity. |
Non-Coeliac Gluten Sensitivity (NCGS) | Digestive symptoms without immune damage | Moderate — varies by individual | Requires care, but generally less sensitive than coeliac |
Wheat Allergy | IgE-mediated allergic reaction to wheat proteins (not only gluten) | Can cause anaphylaxis | Requires full wheat avoidance and emergency protocols |
Dermatitis Herpetiformis | Skin manifestation of coeliac disease | Same as coeliac | Apply full coeliac protocols |
The most important question to ask: "Is this a medical condition like coeliac disease, or a personal preference?" The answer changes how you respond in the kitchen.
Complete Gluten-Containing Ingredients Reference
Category | Ingredients |
Primary sources | Wheat (all varieties: durum, semolina, spelt, kamut, einkorn, emmer), barley, rye, triticale |
Malt products | Malt vinegar, malt extract, malted barley flour, malted milk |
Sauces and condiments | Traditional soy sauce (contains wheat), Worcestershire sauce (often), some mustards |
Hidden sources | Modified food starch (if wheat-derived), hydrolyzed vegetable protein, natural flavourings (check label), some seasoning blends |
Restaurant-specific risks | Shared fryer oil (from breaded items), flour dusting on grill surfaces, pasta water (always use fresh water for GF pasta), shared toasters, and squeeze bottles contaminated by flour. |
Gluten-Free Grains and Flours
Ingredient | Use In | Notes |
Rice flour | Batters, coating, baking | Light, neutral — good all-purpose substitute |
Almond flour | Baking, coating | Rich, nutty, higher fat content |
Chickpea flour (besan) | Savoury batters, fritters, flatbreads | High protein, earthy flavour |
Coconut flour | Baking | Very absorbent — recipes need adjustment |
Tapioca starch | Thickening, baking | Provides chewiness and shine |
Potato starch | Baking, thickening | Light, fluffy texture |
Quinoa | Grain-based, salads | Complete protein, naturally gluten-free |
Buckwheat | Pancakes, noodles, porridge | Despite the name, not related to wheat |
Teff | Bread, porridge | Common in Ethiopian cuisine |
Sorghum | Flatbreads, porridge, beer | Mild flavour, versatile |
Millet | Porridge, side grain | Mild, light, nutritious |
Cross-Contamination Prevention: The Full Protocol
Step | Action Required |
Surface cleaning | Deep clean all surfaces with hot, soapy water before gluten-free prep |
Equipment | Use dedicated cutting boards, knives, pans, colanders, and mixing bowls — colour code them |
Fryer | Use a separate fryer or completely drain, clean, and refill with fresh oil |
Pasta | Always use fresh, clean water — never cook GF pasta in shared water |
Toaster | A dedicated GF toaster is non-negotiable for coeliac guests |
Grill | Clean and re-season the grill before preparing GF proteins |
Hands | Wash thoroughly before any GF preparation — not just change gloves |
Gloves | Change gloves for each GF preparation — never touch flour or bread before handling GF items |
Apron | Change apron before GF prep if flour has been used |
Flour | Keep wheat flour well away from GF prep zones — flour particles become airborne |
Order sequence | Prepare GF items first in the service, before flour-based items |
Sample Gluten-Free Menu Ideas
Course | Dish Idea | GF Check Points |
Breakfast | Quinoa breakfast bowl with fruit, nuts, and coconut milk | Confirm oats are certified GF if used |
Breakfast | Omelette with fresh vegetables and herbs | No flour in filling |
Lunch | Grilled protein salad with olive oil dressing | Confirm dressing is GF |

Lunch | GF pasta with classic tomato or pesto sauce | Dedicated water, dedicated colander |
Main | Grilled proteins with roasted vegetables | No flour dusting or marinades |
Main | Risotto with seasonal ingredients | Confirm stock is GF |
Main | Curry served with rice | Confirm that curry paste and coconut milk are GF |
Dessert | Flourless chocolate cake with almond flour | Confirm no shared baking equipment |
Dessert | Panna cotta with berry compote | Confirm vanilla and cream are GF |
Dessert | Fresh fruit with coconut cream | Naturally GF |
Service Protocol Summary
Stage | Action |
Order taking | Determine whether it is coeliac, sensitivity, or preference. Document clearly on the ticket. |
Kitchen notification | Alert the head chef or senior cook immediately for all coeliac orders |
Preparation | Use the full cross-contamination protocol above |
Quality check | Expeditor inspects the dish before it leaves the kitchen |
Service | Identify the GF dish clearly — never place it on the pass with standard dishes |
At the table | Confirm verbally with the guest which dish is theirs before placing |
Follow up | Check back during the meal — GF guests appreciate reassurance |
