Achieving the ideal consistency for the filling requires attention to the ratio of fat to solid. In my professional experience, the most common error is a dry, crumbly yolk mixture. To combat this, I rely on the emulsifying properties of Dijon mustard combined with full-fat mayonnaise. This creates a velvety mouthfeel that holds its shape when piped.

Furthermore, the acidity is non-negotiable; while some prefer lemon juice, I find that apple cider vinegar offers a rounded sweetness that complements the sulfurous notes of the egg. When searching for ratio benchmarks, I often cross-reference this standard recipe for [classic deviled eggs](https://downshiftology.com/recipes/deviled-eggs/) which aligns closely with the traditional ratios I utilize in my test kitchen.
