This is a Jagarico limited-time flavor that will be released at the time of the plum blossoms (Tokyo's flowering forecast is January 26 / Source: Japan Meteorological Agency). You can enjoy the "(4) combined" taste using four ingredients: plum, honey, sesame oil, and dried bonito flakes.
Based on plum flavor, it has a slightly sweet taste with honey, aroma with sesame oil, and a sweet and sour taste with bonito broth as an aftertaste. In addition, it seems that plum flavor flakes, plum paste, and plum powder are kneaded into the dough so that you can feel the flavor of plums.
