To improve serpentine stool of frozen dessert while suppressing deterioration over time of hardness after removing frozen dessert from freezer.SOLUTION: A plurality of kinds of frozen dessert raw material mix containing a sweetener, a milk component and water and having different freezing points are frozen at a temperature lower than the respective freezing points to separate a plurality of partial frozen compositions A freezing step in which the partial frozen compositions obtained by mixing the plural types of partially frozen compositions are mixed and a freezing step in which the partially frozen compositions are collectively frozen, the frozen points are different from each other To produce an integrated frozen dessert in a state in which a plurality of types of frozen products are mixed.Selection drawing None【課題】冷菓を冷凍庫から取り出した後の硬さの経時低下を抑えつつ、冷菓のサジ通りを向上させる。【解決手段】甘味料、乳成分、および水を含有し、凍結点が互いに異なる複数種の冷菓原料ミックスを、それぞれの凍結点よりも低い温度で凍結させて、複数種の部分凍結組成物を得る部分凍結工程と、前記複数種の部分凍結組成物を混在させる混在化工程と、該混在させた部分凍結組成物を一括的に凍結させる凍結工程を経て、凍結点が互いに異なり乳成分を含有する複数種の凍結物が混在した状態で一体化された冷菓を製造する。【選択図】なし
