This is a Wenshu mandarin jam made using 100% Onshu mandarin oranges grown on the slopes of Minami-Atami overlooking Sagami Bay. Atami City, which is famous as a hot spring tourist destination, also has a sloping land in the Minami-Atami area (Taga and Ajiro), where citrus fruit cultivation is thriving as the sun shines back from Sagami Bay. We used Onshu mandarin oranges grown in the Minami-Atami area and developed it with the hope that it would be a product that conveys the new charm of Atami. Please enjoy this jam packed with the blessings of Atami at home. In addition, we are particular about the manufacturing method. The seasonal deliciousness of Onshu mandarin oranges is carefully simmered in a low-temperature vacuum double kettle that can make the most of freshness with little heat load. The sugar is also made with carefully selected ingredients, such as beet granulated sugar made from sugar beets from Hokkaido, lemon juice and agar using domestic ingredients. It has also been newly certified by the Atami certified brand "Atami Collection A-PLUS" in FY2024 and has been well received.
