The "Butter Butler" is a dessert where butter is the star, made from carefully selected butter from all over the world. It was born out of a desire to bring joy through butter-based sweets during a time of butter shortage at the time of its establishment in 2016. The Butter Butler Financier, a winner of the 1st "JR East Souvenir Grand Prix" Overall Grand Prix, is made with fermented butter from Europe and salt from Guerande, France. The surface of the financier is baked to a crisp, while the inside is moist and blissful. This "butter financier" is made with a recipe that includes two kinds of "European fermented butter" for a rich buttery flavor. The surface is baked to a golden brown, and the finishing touch is soaked in maple syrup from Quebec, Canada, for a moist texture. A little bit of Guerande salt from France is added to enhance the sweetness of the maple syrup. The result is a moist, savory texture and rich buttery flavor.
