A translated phrase card removes the two failure points of eating abroad: the ingredients that are invisible in a dish, and the gap between 'vegetarian' and 'no animal products' in everyday usage.
Why 'I am vegan' is often not enough
In many languages the borrowed word is understood in cities and not in villages, and in several cuisines it is read as a preference rather than a rule. Naming ingredients works far better than naming a category: fish sauce in Thailand, ghee and paneer in India, lard in Central Europe, bonito flakes in Japan, chicken stock nearly everywhere. A card that lists specific exclusions gets a reliable answer where an identity statement does not.
The invisible ingredients by region
East and Southeast Asia: fish sauce, shrimp paste, oyster sauce, dashi made from bonito. South Asia: ghee in breads and rice, paneer, curd, and honey in sweets. Mediterranean and Latin America: lard in pastry and beans, anchovy in dressings, chicken stock in rice. Eastern Europe: pork fat as a cooking base and gelatine in desserts. Knowing your region's three most common hidden items is worth more than a hundred vocabulary words.
Tone matters as much as vocabulary
A card that opens with thanks and frames the request as a question — 'could this be made without…?' — gets far better results than one that reads as a list of prohibitions. In many food cultures hospitality is central, and a request framed as an invitation to help almost always succeeds where a demand does not.
Ordering strategies that work anywhere
Ask what the kitchen already makes without animal products rather than asking them to modify a dish; side dishes, breads, bean and vegetable preparations are often naturally plant-based. Arriving outside peak service, ordering several sides instead of one main, and asking about the cooking fat rather than the ingredient list are the three habits that most reliably produce a good meal.
