🌾 What is einkorn; is it a native wheat?
Einkorn (Triticum monococcum) is a wheat variety with a very long history of cultivation. Yes, it is part of Anatolia's native agricultural heritage: The Royal Botanic Gardens, Kew, record the origin of cultivated einkorn as southeastern Turkey. However, being “native” does not mean it only grows in Turkey. Source: Kew
In Turkey, einkorn is particularly associated with the northern province of Kastamonu and is traditionally used in making bread and bulgur. Bulgur is a grain product prepared by boiling, drying, and cracking wheat. Source: Akademik Gıda
⚠️ “Heirloom” does not mean “gluten-free”
Gluten is the name for proteins found in grains such as wheat, barley, and rye. In celiac disease, gluten consumption causes the immune system to damage the small intestine. Therefore, bread, flour, or bulgur made with einkorn are not alternatives for those who need a gluten-free diet. Source: NHS
🍽️ When ordering in Istanbul
If the menu or packaging states “siyez”, “siyez unu” (einkorn flour) or “siyez bulguru” (einkorn bulgur), remember that the product contains wheat. Do not accept terms like “atalık” (heirloom), “doğal” (natural) or “organik” (organic) as a guarantee of being gluten-free.
If you have celiac disease, you can show the staff this sentence:
“Çölyak hastasıyım. Siyez dahil buğday, arpa ve çavdar yiyemiyorum. Yemeğim bunlarla temas etmeden hazırlanabilir mi?”
“I have celiac disease. I cannot eat wheat, barley, and rye, including einkorn. Can my meal be prepared without contact with these?”
🌱 Being vegan also does not mean it’s gluten-free. Einkorn is plant-based; however, whether a dish prepared with einkorn is vegan depends on its other ingredients.
📌 Save this for your Istanbul trip. Share with a gluten-free friend.
