Sayınlar Fırın is a bakery in Üsküdar that specialises in buckwheat-flour products. Nearly all items on the website are labelled 'Glutensiz' (gluten-free), and the site has dedicated categories for gluten-free breads and pastries. Their buckwheat flour is milled in-house from imported Russian grain, and products are baked in a stone oven using organic flours and natural sweeteners. The product line appears to be entirely gluten-free, strongly implying a dedicated gluten-free kitchen, though the website does not explicitly confirm that no gluten-containing ingredients are on the premises. No external accreditation or independent verification is documented. Recommended for coeliac diners, but advisable to confirm directly with staff whether the kitchen is fully dedicated.
