Swiss rolls, a classic dessert known for their delicate sponge cake and rich fillings, have been a staple in bakeries and households for centuries. However, one common issue that has plagued bakers and cake enthusiasts alike is the tendency of Swiss roll skin to stick to paper. Whether it’s parchment paper, wax paper, or even silicone mats, the skin of the Swiss roll seems to have an affinity for adhering to these surfaces, making it difficult to remove without damaging the cake. But why does this happen, and what can be done to prevent it?
The Science Behind the Stickiness
To understand why Swiss roll skin sticks to paper, it’s essential to delve into the science behind the cake’s composition and the properties of the paper. Swiss rolls are made from a batter that typically consists of eggs, sugar, flour, and butter or oil. When baked, the eggs and sugar caramelize, creating a crispy, golden-brown crust on the outside, while the inside remains soft and spongy. This crust, also known as the “skin,” is the culprit behind the stickiness.
The skin of the Swiss roll is composed of a network of starch molecules, proteins, and sugars that are bonded together through a process called gelatinization. When the cake is baked, the starches absorb moisture and swell, creating a rigid and brittle structure. As the cake cools, the starches retrograde, or recrystallize, forming a crystalline structure that gives the skin its characteristic texture and stickiness.
The Role of Moisture and Humidity
Moisture and humidity play a significant role in the stickiness of Swiss roll skin. When the cake is freshly baked, the skin is still warm and moist, making it more prone to sticking to surfaces. As the cake cools, the moisture evaporates, causing the skin to contract and become more brittle. However, if the cake is exposed to high humidity or moisture, the skin can absorb water and become sticky again.
This is why Swiss rolls are often more prone to sticking in humid environments or when stored in airtight containers. The moisture in the air or the container can cause the skin to become sticky, making it difficult to remove from paper or other surfaces.
The Properties of Paper
The type of paper used can also contribute to the stickiness of Swiss roll skin. Parchment paper, wax paper, and silicone mats are commonly used in baking, but each has its own unique properties that can affect the cake’s skin.
Parchment paper, for example, is coated with a thin layer of wax or silicone that prevents food from sticking to it. However, this coating can also cause the skin of the Swiss roll to stick to it, especially if the cake is still warm or moist.
Wax paper, on the other hand, is coated with a layer of wax that can melt when exposed to heat or moisture. This can cause the skin of the Swiss roll to stick to the paper, especially if the cake is freshly baked.
Silicone mats, which are made from a flexible silicone material, are often used in baking because they are non-stick and easy to clean. However, they can also cause the skin of the Swiss roll to stick to them, especially if the cake is still warm or moist.
The Importance of Cooling and Drying
Cooling and drying the Swiss roll properly can help prevent the skin from sticking to paper. When the cake is freshly baked, it’s essential to let it cool completely on a wire rack before attempting to remove it from the paper. This allows the skin to contract and become less sticky.
Drying the Swiss roll is also crucial in preventing stickiness. If the cake is stored in an airtight container or wrapped in plastic wrap, the moisture can become trapped, causing the skin to become sticky. Instead, it’s best to store the cake in a cool, dry place, such as a cake stand or a wire rack.
Prevention is the Best Solution
While it’s impossible to completely eliminate the stickiness of Swiss roll skin, there are several steps that can be taken to prevent it. Here are a few tips:
- Use a light dusting of powdered sugar or cornstarch on the paper before baking the Swiss roll. This can help prevent the skin from sticking to the paper.
- Use a silicone mat or parchment paper that is specifically designed for baking. These products are often coated with a non-stick material that can help prevent the skin from sticking.
- Make sure the Swiss roll is completely cool before attempting to remove it from the paper. This can help prevent the skin from sticking.
- Store the Swiss roll in a cool, dry place, such as a cake stand or a wire rack. This can help prevent moisture from becoming trapped and causing the skin to become sticky.
Additional Tips and Tricks
Here are a few additional tips and tricks that can help prevent Swiss roll skin from sticking to paper:
- Use a pastry brush to lightly brush the paper with melted butter or oil before baking the Swiss roll. This can help prevent the skin from sticking to the paper.
- Use a piece of parchment paper that is larger than the Swiss roll. This can help prevent the skin from sticking to the paper and make it easier to remove the cake.
- If the Swiss roll does stick to the paper, try gently peeling the paper away from the cake. If this doesn’t work, try dipping the paper in hot water for a few seconds. This can help loosen the skin and make it easier to remove.

What causes Swiss roll skin to stick to paper?
The main reason Swiss roll skin sticks to paper is due to the moisture content in the cake. When a Swiss roll is baked, the heat from the oven causes the eggs, sugar, and butter to release moisture. As the cake cools, this moisture is trapped inside, making the surface of the cake sticky. When the cake comes into contact with paper, the moisture is drawn out, causing the cake to stick.
To minimize the sticking, it’s essential to ensure the cake is completely cooled before handling it. You can also try dusting the cake with a small amount of powdered sugar or cornstarch to absorb excess moisture. Additionally, using parchment paper or a silicone mat can help prevent sticking, as these materials are designed to be non-stick.
How can I prevent Swiss roll skin from sticking to paper?
