Cide Walnut Halva

Cide walnut halva is a traditional halva variety long associated with the Cide district of Kastamonu Province, produced locally for many years. It has been registered as a Geographical Indication by the Turkish Patent and Trademark Office. This halva is prepared using beet sugar, water, egg white, citric acid, and a substantial quantity of walnut kernels; its production takes approximately 3.5 to 4 hours.

It has become part of local customs, such as men bringing halva to homes during special visits like engagement proposals or after holiday prayers. Due to its strong association with the region, all stages of production must be carried out exclusively within the Cide district of Kastamonu.

Product Characteristics

Cide walnut halva is a mixture composed of beet sugar, egg white, citric acid, and walnuts. Its distinctive qualities are achieved by removing the sugar syrup from the heat at a critical temperature range of 140 °C to 145 °C, ideally at 143±2 °C. Syrup prepared outside this temperature range fails to achieve the desired consistency or results in an undesirable appearance. Continuous stirring during the syrup stage is essential to prevent caramelization of the sugar and to ensure even evaporation of water.

The egg white used in the product imparts a glossy appearance and prevents the halva from crumbling when cut, despite its firm texture. Only citric acid (lemon salt) is used to extend shelf life. One of the distinguishing features of Cide walnut halva is that it does not produce a burning sensation in the throat during consumption and does not stick to the teeth while chewing.

The physical and chemical properties of the halva must meet the following values: fat content must be approximately 2.10±0.20%, protein content approximately 9.15±0.25%, and walnut kernel content must be at least 40%. Total sugar (expressed as sucrose) must not exceed 40%, and moisture content must not exceed 8.50%.

Production Method

The production process of Cide walnut halva requires precise proportions of ingredients and strict adherence to specific temperatures. The primary raw materials are walnut kernels, natural beet sugar, egg white, and citric acid.

The production steps are as follows:

• Sugar and water are thoroughly mixed in boiling vessels and boiled for approximately four hours. Citric acid is added to the mixture during this boiling stage.
• Once the mixture reaches the critical temperature of 143±2 °C, it is removed from the heat and allowed to cool to 40±5 °C.
• Whipped egg white is added to the cooled mixture.
• The mixture is returned to the heat and stirred continuously for approximately two hours until it achieves a "chewing gum" consistency.
• Finally, walnut kernels are added while the mixture is still hot, ensuring they constitute at least 40% of the final product.

The optimal temperature for cutting and slicing the final mixture is around 18–22 °C; complete cooling makes cutting difficult. The halva is placed in containers for storage and sale and allowed to rest. It is recommended that the product be consumed or put on sale one day after production to achieve its ideal texture. Storage should be maintained at approximately 20 °C, though refrigeration is acceptable during the sales phase.

Geographical Boundary

The geographical boundary of Cide walnut halva is the Cide district of Kastamonu Province. The product’s long-standing history and the specialized craftsmanship required for its production have established its reputation exclusively with this region. Therefore, all production, processing, and related operations must be conducted within the boundaries of the Cide district.

Monitoring

Compliance with the registered characteristics of Cide walnut halva is monitored by a control body established under the coordination of the Cide Municipality. This body consists of four representatives: the Cide Municipality, the Cide District Directorate of Agriculture and Forestry, the Cide Chamber of Tradesmen and Craftsmen, and the Cide Municipality Security Directorate.

Inspections are conducted regularly at least once per year, with additional inspections carried out in the event of complaints. The control body evaluates all stages of the process, including the characteristics of the raw materials (walnuts), adherence to the registered production technique, and storage conditions. Reports on inspection results are submitted to the Turkish Patent and Trademark Office in accordance with applicable regulations. The Cide Municipality, as the registering entity, is responsible for initiating legal proceedings to protect the product’s rights.
