A new seasonal tart has arrived at Ducky Duck. Starting March 14, 2026, the "Kagoshima Dekopon and Mascarpone Tart" will be available at Ducky Duck locations and a number of affiliated shops through late April.
The dekopon used in this tart comes from JA Kagoshima Izumi and has cleared strict quality standards — a sugar content of at least 13 degrees and acidity of 1% or less, verified by optical sensor. The result is a citrus fruit with a satisfying bite, generous juice, deep sweetness, and just the right amount of tartness.
To complement the bold flavor of the dekopon, the tart is topped with mascarpone cream, prized for its milky, refined taste. The combination brings together the bright, fresh aroma of citrus and the lush creaminess of the cheese, making it a fitting treat for the spring season.
