'Toyohashi Neapolitan Sauce' is a retort food produced in our own factory within the city, abundantly using ingredients from Toyohashi City under the theme of 'local production for local consumption.' Through this registration as a hometown tax return gift, we will deliver the charm of Toyohashi to everyone nationwide through 'food.'

■ A plate of 'Toyohashi's blessings'! Commitment to 'local production for local consumption'

Toyohashi City, Aichi Prefecture, is blessed with a mild climate and vast land, boasting one of the highest agricultural production values in the country. 'Toyohashi Neapolitan Sauce' uses local ingredients grown in the city, such as onions, tomatoes, and quail eggs. In particular, quail eggs are a specialty product for which the city boasts the highest production volume in Japan. In this product, two quail eggs are used in the sauce to create a visually appealing 'ingredient-rich' feel that is satisfying to eat. In addition, the bacon used is made from pork produced in Toyohashi and manufactured in the city. This product is a local Neapolitan sauce that pays special attention to each ingredient, packing the 'essence of Toyohashi' and literally condensing 'Toyohashi's blessings' into one plate.

■ Completed over a year with about 100 prototypes! Aiming for a taste you wouldn't believe is retort

In order to maximize the deliciousness of the ingredients, the cooking process uses as little water as possible, adopting a simmering method that utilizes the moisture released from the vegetables.

It features a fragrant and rich taste in which the refreshing acidity of tomatoes, the sweetness of onions, and the richness of bacon are harmonized. In addition to mixing it with noodles, it can be used for a wide range of arranged menus such as omurice, gratin, and doria.

The development of this product started with the desire to 'communicate the charm of local Toyohashi through food' under the theme of regional contribution. Toyohashi City is blessed with a mild climate and is a production area where fresh tomatoes are harvested, so we started developing 'Neapolitan Sauce' with the idea of making a menu that uses a lot of tomatoes and a retort food that can be paired with noodles.

The development period was about one year. The number of prototypes repeated while assessing changes in taste due to retort processing reached about 100. Retort foods have the difficulty that their flavor easily changes due to the heat sterilization process. Therefore, we adjusted the blending while anticipating the taste after processing, and by repeating prototyping and improvement, we finished it into a satisfying taste. 'While being a retort food that can be easily eaten at home, we want it to be a product that firmly conveys the charm of Toyohashi.' This is a dish packed with our company's feelings.

■ To the whole country as a hometown tax return gift

With this hometown tax return gift registration, 'Toyohashi Neapolitan Sauce' is now available on 'Rakuten Furusato Nozei'...
