Gateway to Sustainability in Japan

Upcycling discarded sweet potatoes into delectable “Pure Sweet Potato Pie”

A longstanding greengrocer with a history spanning over six decades has successfully upcycled non-standard sweet potatoes into a delightful dessert called “Pure Sweet Potato Pie.” While sweet potato consumption has surged amid an unprecedented boom, countless sweet potatoes are discarded due to factors like excessive size or the presence of blemishes.

In a bold move to repurpose these sweet potatoes, the greengrocer partnered with a pie specialty shop to transform them into sweets. The process involves aging the non-standard sweet potatoes and baking them in a unique pot, which enhances their sweetness and results in a smooth, rich texture. The collaboration between the greengrocer and the pie shop saw professionals from both fields contributing their expertise and engaging in trial and error to optimize the ingredients’ flavors.

The final product retains the sweetness and texture of the sweet potatoes while appealing to a broad demographic. The “Pure Sweet Potato Pie” dessert offers a melt-in-your-mouth experience that maintains the smooth, rich essence of the original ingredient, providing a truly unique taste sensation.

Despite being delicious, a significant number of sweet potatoes are discarded due to variations in size and superficial imperfections. By slowly baking them in a specially designed pot, the conversion of starch into sugar is prolonged, leading to an even sweeter and smoother end product.

This upcycling initiative not only makes these treats more accessible but also appeals to younger consumers. Repurposing sweet potatoes that would have otherwise been discarded benefits both the greengrocer and the farmers, with the generated revenue paving the way for new employment opportunities and further growth. The ultimate goal is to produce sustainable products that give back to everyone involved in the process.
