Marude Mitsuimo is designed to resemble biting into a chilled honey-sweetened roasted sweet potato. The outer layer uses Beni Haruka, known for its sweetness and sticky texture, while the vanilla center softens the flavor and adds a creamy contrast. The larger 68 ml serving gives the ice cream bar a more substantial feel than the previous 65 ml format.
Imuraya Rich Sweet Potato Ice Cream takes a more layered approach. The base uses Imuraya’s sweet potato paste made with Japanese Beni Haruka, followed by ice cream made with the same sweet potato paste and Hokkaido cream. Direct-fire browned butter adds aroma to the ice cream, while bittersweet caramel sauce creates contrast.
A layer of cookie crunch completes the four-part structure with a crisp texture. The sweet potato paste is slowly cooked to draw out its concentrated flavor, making the product closer to a rich sweet potato dessert than a simple flavored ice cream.
The two ice creams are intended to offer different ways to enjoy the autumn sweet potato flavor. Marude Mitsuimo focuses on the contrast between a dense outer layer and vanilla center, while the Imuraya product combines paste, cream, caramel, and crunch in one bar. Store prices may vary, and some locations may have different product availability or specifications.
