Morinaga Seika Co., Ltd. (Shibaura, Minato-ku, Tokyo; President and COO Shin'ya Mori) will release "Mamire ", an experiential cup ice cream designed to be "sauce-drenched" and featuring a non-freezing, gooey sauce even when frozen, for a limited time at convenience stores nationwide starting May 18, 2026 (Monday).
This product is a cup ice cream developed with the aim of recreating "the deliciousness of pudding with plenty of caramel sauce, as served in a restaurant," by generously topping custard ice cream with caramel-flavored sauce. A layer of crispy white chocolate is placed between the ice cream and the sauce, allowing consumers to enjoy changes in taste and texture with every spoonful. This product was also developed over approximately four years of consideration and prototyping as an "experiential ice cream" that allows consumers to enjoy the process of eating itself. By achieving a gooey sauce that does not freeze even when frozen, it offers a new ice cream experience that naturally immerses consumers in eating from the first spoonful to the last bite. Furthermore, a patent* has been obtained for the manufacturing method of this product, which allows the consumer to enjoy the taste of the sauce until the very end. Through the launch of this product, we aim to propose new ways to enjoy ice cream and deliver memorable moments and smiles to our customers. *Patent No. 7809237
■ Development Background
Focusing on a new trend: "Experiential Ice Cream" – valuing the process of eating
In recent years, with the spread of social media and video platforms, an environment has expanded where people routinely enjoy fast-paced videos and music.
As the speed of information consumption accelerates, with the generalization of fast-forward viewing and the shortening of songs, there is a growing preference for enjoying changes and contrasts as an "experience." Against this backdrop, we believe that in the ice cream market, "experiential ice cream" – which allows consumers to enjoy changes from the beginning to the end of eating, not just the taste – will attract attention as a new value. Focusing on this trend, we have started a new project to develop an ice cream that changes its expression as you eat it, while luxuriously enjoying a gooey sauce.
■ Development Process (Secret Story of Development)
The concept: "Sauce-Drenched Ice Cream" – an "Immersive Experience" with a non-freezing, gooey sauce
Approximately four years ago, the development of this product began with a simple desire from the project team: "We want to create a 'sauce-drenched ice cream' that allows consumers to fully enjoy the presence of the sauce and want to keep eating until the end." The concept was set as "I want to drown in a sea of sauce. A decadent, sauce-drenched ice cream where caramel sauce fills you to the very end." However, reducing the sweetness of the sauce and achieving mass production quality with a large amount of non-freezing, gooey sauce presented significant challenges.
During the development process, we repeatedly reviewed sauce formulations and structural designs, conducted on-site prototyping and verification, and addressed each issue, such as "why does it freeze?" and "why is the structure unstable?", making continuous adjustments. In particular, establishing a 3-layer structure of ice cream, chocolate, and gooey sauce, and designing it to maintain the presence and balance of the sauce throughout the eating process, was a time-consuming process from both technical and manufacturing perspectives. After repeated prototyping and consideration, the "sauce-drenched" immersive experiential ice cream with a non-freezing, gooey sauce was completed. The product was named "Mamire" because it is an ice cream "covered in sauce." The development took approximately four years.

● Recommended way to eat
・First, scoop the gooey sauce on top and directly enjoy the fragrant taste of caramel.
・As you eat, "mix and entangle" the sauce, custard ice cream, and white chocolate to enjoy the changes in taste and texture.
・Recommended for relaxing time at the end of the day or as a reward for yourself after working hard.
■ Comment from the "Mamire" Project Team, Research Institute Representative
General ice creams with sauce tend to harden immediately after freezing and contain only a small amount. The development started from the team members' desire to "eat ice cream with plenty of sauce!" This product offers plenty of gooey sauce right out of the freezer. We aim to deliver surprise and感動 with the gooey texture the moment it's opened.
Quality to be maintained.
