Navigating Shellfish-Free Dining in Portugal: A Traveler's Guide
Portugal’s coastline location means seafood dominates many menus, presenting challenges for travelers with shellfish allergies. While dishes like amêijoas à Bulhão Pato (clams) and cataplana de marisco (seafood stew) are iconic, hidden shellfish ingredients lurk in stocks, sauces, and even rice dishes. Thankfully, with awareness and smart tools like mm food, you can savor Portugal’s cuisine safely.
Common Shellfish Pitfalls in Portuguese Cuisine
- Sopas de Marisco: Seafood soups often contain shrimp or crab bases.
- Arroz de Marisco: Rice cooked in shellfish broth, sometimes with added crustaceans.
- Prego (steak sandwich): Occasionally served with prawn-infused butter.
- Fish Stews & Grills: Cross-contamination is common in kitchens.
- Hidden Dangers: Fish stock, caldeirada (fish stew), and even some sauces may use shellfish derivatives.
Key Communication Phrases
Equip yourself with these phrases:
- "Tenho alergia a marisco" (I’m allergic to shellfish).
