Why use baking powder in cakes and honeycomb?

Baking powder plays a crucial role in both cakes and honeycomb, though for different reasons:

In Cakes:

* Leavening agent: Baking powder provides the "lift" in cakes, creating the airy, light texture we all love.

* Chemical reaction: When baking powder is mixed with wet ingredients, it releases carbon dioxide gas. This gas gets trapped in the batter, expanding and creating air pockets that make the cake rise and become fluffy.

* Type of baking powder: Double-acting baking powder releases a bit of carbon dioxide when mixed with wet ingredients and the rest when heated in the oven, ensuring consistent rise.

In Honeycomb:

* Structure and texture: Baking powder is essential for the honeycomb's signature crispy, airy texture.

* Expansion: When heated, the baking powder releases carbon dioxide gas, creating the honeycomb-like structure with its many air pockets.

* Flavor: While not the primary reason, baking powder can add a slightly tangy flavor to honeycomb.

Here's a breakdown of how each ingredient contributes to the final product:

Cake:

* Baking powder: Adds air and structure, resulting in a light and airy cake.

* Flour: Provides the framework for the cake and binds the other ingredients together.

* Sugar: Adds sweetness, moisture, and helps with browning.

* Eggs: Bind the ingredients, add richness, and contribute to the cake's structure.

* Fat: Provides moisture, tenderness, and richness.

Honeycomb:

* Baking powder: Creates air pockets for the honeycomb's characteristic texture.

* Sugar: Provides sweetness and forms the honeycomb's structure.

* Golden syrup: Adds moisture and helps to prevent crystallization.

* Bicarbonate of soda: Contributes to the airy structure.

In essence, baking powder is a versatile ingredient that plays a crucial role in both cakes and honeycomb, contributing to their unique textures and flavors.
