Storage Methods and Blending Tips for Winter Wagashi Ingredients
Appropriate storage methods for seasonal materials
To make winter wagashi ingredients last, proper storage methods are important.
Processed yuzu products basically require refrigerated or frozen storage. Store yuzu slices, yuzu jam, and fresh yuzu paste refrigerated, and freeze yuzu juice to preserve its fresh flavor. It is ideal to use them up quickly after opening, but transferring them to an airtight container helps maintain quality.
Store sarashi-an and adzuki an unopened in a cool, dark place. After opening, refrigerate and use them up within about a week. Candied chestnuts and candied plums should also be refrigerated after opening as a rule. Starches can maintain quality over a long period when kept away from moisture and stored at room temperature in an airtight container.
Blending Tips Practiced by Professionals
To finish winter wagashi deliciously, the balance in blending ingredients is important.
In wagashi made with yuzu, too strong a yuzu aroma spoils the flavor of the an, so it is ideal to keep yuzu paste or yuzu juice to about 5 to 10% of the an. When adding yuzu to adzuki an, it pairs well with koshi-an, giving a flavorful aftertaste. With tsubu-an, the acidity of the yuzu brings out the flavor of the adzuki.
In wagashi made with chestnut, consider the balance between the sweetness of the candied chestnuts and the sweetness of the an. Extra-soft grades melt readily in the mouth, making them ideal as an ingredient for yokan and manju. First-grade products suit wagashi that showcase the chestnut's shape. In water confections made with starches, the texture changes greatly depending on the blending ratio of pure bracken starch or hon-kuzu, so it is important to make repeated trial batches to find the optimal blend.
