To jump start my mornings, I absolutely love getting that creamy dollop of milk foam topping on my morning cappuccino. Sometimes, though, you just don’t have enough time or energy to pop into your local coffee shop, even if it’s just a block or two away!
Luckily, you don’t really need to because did you know that you can make milk foam at home? And without needing a fancy espresso maker? All you need is some milk, a clean jam jar with a lid, and a microwave.
Yep, that’s all you need to make milk foam at home!
How Does This Work?
Making milk foam in the microwave is a two-step process:
First, you shake the milk vigorously in a jar to create foam.
Second, you microwave it for a few seconds to stabilize the foam.
Without the microwaving step, the milk foam will quickly collapse back into the milk.
What Kind of Milk Should I Use?
If there is one place and time where you should use low-fat milk, it’s making milk foam at home! Low-fat milk varieties such as 2% and non-fat contain whey proteins that act as “stabilizers”, which hold the foam and keep them in place when heated.
I’ve have tried this microwave method with different types of milk:nonfat milk, 2% milk, whole fat milk, and even heavy cream, and based from my experience, it’s the nonfat and 2% milk that win every time. They both come out of the microwave with impressive stacks of foam that look like they were made with an actual espresso machine!
Using the Milk Foam
After the milk foam has been stabilized in the microwave, it is so thick that you can literally spoon it into your coffee mug.
If you want to add a little of the warmed milk as well, simply use your spoon to hold back the foam while you pour a little into your coffee, then spoon the foam on top, barista-style.
If there is one caveat with making milk foam without using a legitimate espresso maker, it’s that milk done using the microwave method is not as stable or long-lasting. In fact, the foam will start to dissipate within a few minutes, so make sure to use the foam immediately.
