This is an easy recipe for a chewy red bean jelly using canned red bean paste. Using gelatin gives it a unique soft and chewy texture that is different from agar-agar. Simply mix red bean liquid (made by simmering red beans in soy milk and brown sugar) with softened gelatin, pour into a mold, and chill until set. It's a comforting, nostalgic Japanese-style dessert that's perfect for summer.
