Oak Gall Nut

Oak acorn flour is a natural flour obtained by grinding the seeds, known as acorns, of oak trees (Quercus species). Historically, this flour served as an important food source in many cultures and is now regaining attention both in traditional cuisines and among those pursuing alternative healthy lifestyles. Due to its nutritious composition and resilience, oak acorn flour played a vital role in human nutrition during periods of scarcity or harsh environmental conditions.

The oak tree and its acorns have held an important place throughout history in regions including Anatolia, Europe, North Africa, and Asia. In ancient times, acorns were a staple food, especially during periods when agriculture was absent or limited. In Greek, Roman, and Ottoman cuisines, local populations consumed them as flour or purée. Acorns were also used as animal feed.

In rural areas of Anatolia, people processed acorns into flour to make bread, soup, and purées. Today, oak acorn flour is experiencing renewed interest as a gluten-free and natural alternative.
