Hello, I'm Dr. Emily Carter, a food scientist specializing in culinary chemistry and flavor profiling. I'm happy to help you understand the difference between salad dressing and mayonnaise.

While both salad dressing and mayonnaise are commonly used to add flavor and moisture to salads, they are distinct in their ingredients, texture, and flavor profiles.

Mayonnaise is an emulsion of oil, eggs, and an acidic ingredient, usually vinegar or lemon juice. The key to mayonnaise is its emulsification process, where the oil droplets are suspended in the water-based egg yolk mixture, creating a creamy, stable consistency. The emulsion is achieved by whisking or blending the ingredients until a smooth, thick texture is achieved. The emulsifier in mayonnaise is the lecithin found in egg yolks.

Salad dressings encompass a broader range of ingredients and textures, and often include a variety of flavors. They can be based on oil and vinegar, creamy dressings based on mayonnaise, or even yogurt-based dressings. While mayonnaise itself can be considered a type of salad dressing, not all salad dressings are mayonnaise.

Here's a breakdown of the key differences:

Ingredients:

* Mayonnaise: Oil, eggs, vinegar or lemon juice, salt, and sometimes spices.
* Salad Dressings: Oil, vinegar, lemon juice, herbs, spices, sweeteners, mustard, yogurt, buttermilk, sour cream, and other flavoring agents.

Texture:

* Mayonnaise: Smooth, creamy, and thick.
* Salad Dressings: Can be thin and runny, creamy, or thick depending on the ingredients and preparation method.

Flavor:

* Mayonnaise: Typically has a mild, slightly tangy flavor, with a creamy richness from the eggs and oil.
* Salad Dressings: Wide range of flavors, from tangy and acidic to sweet and creamy. Some common flavor profiles include:
* Vinegarette: Tangy and acidic, with a balance of oil and vinegar.
* Creamy: Rich and creamy, often with a base of mayonnaise, yogurt, or sour cream.
* Sweet and Sour: A combination of sweetness and acidity, often with honey, sugar, or fruit.

Applications:

* Mayonnaise: Primarily used as a condiment for sandwiches, salads, and other dishes. It can also be used as a base for other salad dressings.
* Salad Dressings: Specifically designed for salads, but can also be used as marinades, dipping sauces, or drizzles for other dishes.

Examples:

* Mayonnaise: Hellmann's, Duke's, Kewpie
* Salad Dressings: Thousand Island, Ranch, Caesar, Balsamic Vinaigrette, Honey Mustard

In conclusion, while mayonnaise is a type of salad dressing, not all salad dressings are mayonnaise. The key difference lies in their ingredients, texture, and flavor profiles. Mayonnaise is a creamy, emulsified mixture of oil, eggs, and vinegar, while salad dressings can encompass a wide range of flavors and textures based on various ingredients.
