But remember, when making substitutions be sure to measure accurately for best results. Many of the ingredient substitutions, especially the worcestershire sauce substitute and mayonnaise substitute, may alter slightly the taste, texture, weight, or moisture content of your finished product. Some may alter your recipe more than others so you need to consider the other ingredients in your recipe when making a dijon mustard substitute or any other recipe substitute. For example, egg salad and tuna salad are very different without real mayonnaise.

A note regarding Substitutions...
Using these substitute suggestions may slightly alter the taste, texture or appearance of your resulting recipe. However, we recommend these substitutions as similar replacement ingredients when the original ingredients are unavailable.
