Frequently Asked Questions (FAQs)
What is overrun, and why is it important?
Overrun refers to the amount of air incorporated into the soft serve during the freezing process, expressed as a percentage increase in volume. It’s important because it significantly affects the texture and mouthfeel. Higher overrun results in a lighter, airier product, while lower overrun leads to a denser, heavier texture. Most commercial operations aim for an overrun between 40% and 60%.
Can I use any type of milk for my soft serve mix?
The type of milk used affects the final product’s texture and flavor. Whole milk contributes to a richer, creamier texture due to its higher fat content. Lower-fat milk, such as 2% or skim milk, will produce a lighter, less creamy soft serve. Experiment with different milk types to find the perfect balance for your taste preferences.
How do stabilizers improve soft serve texture?
Stabilizers, such as guar gum or carrageenan, prevent ice crystal formation and improve the overall texture of soft serve. They help to bind water molecules, creating a smoother, more consistent product that is less prone to graininess. Using stabilizers in the right amount is crucial for achieving optimal texture.
