Sour cream is a perfect replacement for mayonnaise in deviled eggs. With its rich and creamy texture, it is a binder made from dairy instead of eggs.

Sour cream contains milk fats instead of oil, yielding a lighter mixture than mayonnaise. The result is far more tart than mayonnaise, adding variety to the deviled egg recipe.

Various types of sour cream are available in grocery stores. The higher the fat content in sour cream, the tangier its flavor, so selection should be made accordingly.

The coolness of sour cream balances the spiciness of chili, a rationale that also applies to mustard and paprika. Adding bacon, green onion, or chive creates a harmonious pairing.
