The invention belongs to the technical field of foods and
processing technologies and in particular relates to a blueberry
wine residue liquor-saturated date steamed bun and a preparation method thereof. The blueberry
wine residue liquor-saturated date steamed bun is prepared from 800-1200 parts of
wheat flour, 100-200 parts of blueberry
