Hidden Gluten
It's rarely in the bread. It's in the stock, the pan, and the cube nobody thinks to mention.
Most of the gluten a celiac traveler encounters abroad is not in the bread. It is in the stock, the marinade, the pan the fish was dusted in, and the cube someone dropped into the soup without thinking of it as an ingredient. None of it appears on a menu. Almost none of it is deliberate.
“Naturally Gluten-Free” Is Not a Safety Claim
It’s a statement about an ingredient.
Rice contains no gluten. Neither do potatoes, corn, chickpeas, fish, or beef. This is a fact about what a food is, and it says nothing at all about the dish that arrives at the table — which passed through a kitchen, a pan, a sauce, and a set of hands on its way there.
A risotto is naturally gluten-free until it is made with a stock cube. A grilled fish is naturally gluten-free until it is dredged in flour before searing, which in Italy is the default technique, not an embellishment. A bowl of bean soup is naturally gluten-free until a cook reaches for the bouillon they reach for every single time.
Naturally gluten-free describes an ingredient. It has never described a plate.
The Ancient Grain Problem
The trouble with this misconception is that it sounds informed.
Farro, in Italian, is not a grain. It’s a family of them — einkorn, emmer, and spelt. All three are wheat. All three contain gluten. So do kamut and khorasan, which are the same thing under two names. So does triticale, a wheat-rye hybrid. None of these is a lower-gluten option, a gentler option, or a more digestible option for a celiac. Several of them are the oldest wheat humans have.
The confusion has three sources, and they compound. Food writing calls them “ancient grains” without saying they’re wheat. Wellness marketing implies that older means kinder. And restaurant menus present them as the healthy, artisanal, thoughtful choice — which they may well be, for everyone who isn’t celiac.
Zuppa di farro is a beautiful Umbrian dish and entirely off-limits. Insalata di farro is on every agriturismo menu in summer. Spelt bread is the pride of a good bakery. All wheat.
Ancient grains are not lower in gluten. Several of them are simply older wheat.
One related trap worth carrying: orzo. In English it’s a small rice-shaped pasta. In Italian it means barley. Both contain gluten, so the confusion is survivable — but the word means different things on either side of a menu, and that’s worth knowing.
The Oat Question
Oats do not contain gluten. Oats are, almost everywhere, contaminated with it.
The problem is agricultural rather than botanical: oats are grown in rotation with wheat, harvested with the same equipment, and milled in the same facilities. The result is that ordinary commercial oats routinely test well above the threshold. Certified gluten-free oats — grown, harvested, and milled separately, then tested — are a different product, and they are safe.
The complication: a minority of celiacs react to avenin, the oat protein itself, even when the oats are certified. Italy’s AIC advises caution with oats generally. This is one of the few places where the correct answer is genuinely individual rather than universal.
Practically: oats are safe only when the label says they’re certified gluten-free, and even then they’re worth introducing carefully.
Where It Actually Hides
The single most under-recognized source of gluten in European kitchens. Most commercial bouillon contains wheat starch or wheat-derived maltodextrin, and it goes into soups, risotti, braises, and stews as a matter of habit. A restaurant that describes its broth as house-made is often describing a broth that was fortified with a cube.
Standard soy sauce is made with wheat. It has travelled into kitchens that have no Asian tradition at all — commercial gyros marinades, Spanish fusion tapas, glazes, dressings. Tamari is the wheat-free version, and it is rarely the default.
Flour is the oldest thickener there is. Gravies, roux-based sauces, béchamel — and béchamel is the structural core of the croqueta, which means every croqueta in Spain is wheat twice over: once in the binding, once in the crumb.
Infarinare — flouring a protein before searing — is a default technique, not a flourish. Scaloppine, fish, veal, cutlets. The flour is invisible in the finished dish and it is on the menu nowhere.
Meatballs, ćevapi, sausages, burgers, terrines. “It’s just meat” is usually said in good faith and is frequently untrue: breadcrumb and soaked bread are traditional binders across most of Europe.
Gazpacho, salmorejo, ajo blanco, ribollita, sopa de ajo. Several of these are structurally bread — remove it and the dish ceases to exist. This is not an optional garnish that can be left off.
Barley-derived and never distilled, which is what separates it from every distilled spirit. It hides in dressings, condiments, and sauces.
If the source isn’t named, it may be wheat. EU labelling requires the source to be declared when it’s an allergen — so modified wheat starch is a clear no, and modified corn starch is fine. Outside the EU, the label may not tell you.
What Doesn’t Count as an Ingredient
A cook can tell you the truth about a dish and still be wrong about it.
A traveler asks whether there’s anything in the bean soup. The cook says no — beans, vegetables, oil, that’s all. The cook is being entirely honest. The cook is also wrong, because half an hour earlier they dropped a bouillon cube into the pot, and a bouillon cube is not, in their mind, an ingredient. It’s seasoning. It’s what you do. It is as invisible to them as salt.
The most dangerous answer in a kitchen is a sincere one.
This is why the useful questions are never “does this contain gluten?” A cook who has never had to think about gluten will answer that question honestly and incorrectly. The useful questions are specific and mechanical, and they name the thing.
Is there a stock cube in this?
Is the fish floured before it’s cooked?
Is there bread in the soup?
Is the meat bound with anything?
Those questions get answers. The general one gets reassurance.
We don’t ask whether a dish is gluten-free. We ask what went into it.
