Does ice make milkshakes thicker?

Answered by Jeremy Urbaniak

When it comes to making milkshakes, many people believe that adding ice will make the shake thicker. However, this is actually a common misconception. In reality, adding ice to a milkshake can have the opposite effect and actually thin out the shake.

The reason for this is quite simple. Ice is made up of frozen water, and when it comes into contact with the milkshake, it begins to melt. As the ice melts, it turns into liquid water, which in turn dilutes the milkshake. This dilution causes the overall consistency of the shake to become thinner.

To illustrate this, let’s imagine you are making a milkshake by blending together ice cream, milk, and some flavorings. Initially, the ice cream is thick and creamy, giving the milkshake a rich consistency. However, as you add ice to the blender, it begins to melt and mix with the other ingredients. This added water content from the melted ice will gradually thin out the shake, making it less thick and more watery.

Now, you may be thinking, why not just use less ice to prevent this thinning effect? While reducing the amount of ice can help minimize the dilution, it still won’t change the fact that the ice will eventually melt and thin out the milkshake. Even if you blend the shake with only a small amount of ice, it will still melt and contribute to the overall thinning of the shake.

It’s important to note that the thinning effect of ice is not limited to milkshakes. It applies to any drink or mixture that contains ice. This is why when you order a cold drink with ice at a restaurant, it often starts off thick and cold but gradually becomes watered down as the ice melts.

To avoid this thinning effect and maintain a thicker milkshake, there are a few alternatives to using ice. One option is to freeze the milk or the ice cream itself before blending. By using frozen ingredients, you can achieve a thicker consistency without the need for ice.

Another option is to use ingredients that naturally thicken the milkshake, such as yogurt, frozen bananas, or powdered milk. These additions can help create a thicker texture, even in the absence of ice.

Contrary to popular belief, adding ice to a milkshake will not make it thicker. Instead, the ice will melt and contribute to the thinning of the shake. To achieve a thicker consistency, it is best to avoid using ice and instead opt for frozen ingredients or other thickeners.
