Half-and-Half (Best Option)
1 cup per 1 cup whole milkHalf-and-half contains about 10-12% fat, which is closer to whole milk's 3.5-4% fat but adds extra creaminess beneficial in soups. The fat content helps emulsify the soup, preventing separation and maintaining a smooth texture.
When using half-and-half, gently heat the soup to avoid curdling and stir frequently. It integrates well with both broth-based and cream-based soups.
The final soup will be slightly richer and creamier than with whole milk, enhancing mouthfeel without overpowering flavors.
