Now, about your question on mayonnaise in cake. It might sound strange at first, but using mayonnaise in cake isn't as unusual as it seems. While not a traditional ingredient, mayonnaise can actually offer some unique benefits in cake recipes, primarily due to its composition of oil, eggs, and acid.

Let's break it down:

**Mayonnaise as a Substitute for Oil and Eggs:**

Mayonnaise is primarily made of oil, usually a neutral-tasting one like canola or soybean oil. This oil serves the same purpose in a cake as adding oil directly - providing moisture, tenderness, and a soft crumb. The eggs in mayonnaise also contribute to the cake's structure and richness. So, in essence, using mayonnaise can be a convenient shortcut, combining the roles of oil and eggs in one ingredient.

Enhancing Moisture and Texture:

The emulsification process used to make mayonnaise creates a stable mixture of oil and water, which can result in a moister and more tender crumb in cakes. The fat content in mayonnaise helps retain moisture, preventing the cake from drying out too quickly.

Adding Flavor Nuances:

While mayonnaise is primarily known for its creamy texture and neutral flavor, it can subtly contribute to the cake's overall taste. The tanginess from the vinegar or lemon juice in mayonnaise can add a slight depth of flavor, balancing out the sweetness and richness of the cake.

Considerations When Using Mayonnaise:

* Flavor Impact: While subtle, mayonnaise can impart a slight tang to the cake. Choose a brand with a neutral flavor profile, and if you're concerned about the taste, start with a small amount and adjust according to your preference.
* Recipe Compatibility: Mayonnaise works best in recipes that already call for oil and eggs. Substituting it in recipes that rely on butter for flavor and texture might not yield the desired results.
* Overall Fat Content: Be mindful of the fat content when substituting mayonnaise, as it can be higher than using separate oil and eggs. Adjust other ingredients accordingly to maintain the recipe's balance.

Experimenting with Mayonnaise in Cakes:

If you're intrigued by the idea of using mayonnaise in cakes, I encourage you to experiment! Start with a trusted recipe that uses oil and eggs, and substitute the oil and some of the eggs with an equal amount of mayonnaise.

Remember, baking is a science and an art. Don't be afraid to explore new techniques and ingredients to discover unique flavors and textures. Happy baking!

Mayo is essentially oil, vinegar, and egg, and while you could just add an extra egg to try and get the same effect, The Kitchn points out that the oil makes the cake tender, the egg helps the batter retain moisture, and the acid in the vinegar really brings out the chocolate flavor.read more >>
