How to Froth Milk with a Mason Jar
Here is a popular method of making frothed milk that only requires a mason jar and a microwave. It is super simple and can be done with things you probably have on hand. Plus, anything done with a mason jar is trendy and hipster, right!?
What you’ll need
A 500 ml Mason jar with a lid
- We suggest heating the milk an a microwave, as this is the simpliest method
- Alternatively, you can heat the milk on the stovetop. To do this, heat the milk in a saucepan and then pour it into the mason jar.
- One of the biggest mistakes people make when frothing is overheating the milk. Milk scalds easily, and scalded milk does not taste pleasant in coffee. Therefore, we highly recommend that you start out using a thermometer. Using a thermometer, you can determine how long you need to microwave the milk (the time will vary depending on the power of your microwave and how cold your fridge is). Once you have determined the correct time, you can ditch the thermometer.
- Almost any kitchen thermometer will work, we found that a digital instant read thermometer was the easiest to use
- Any kind of milk will work, but the higher the fat content the better the milk will froth
- You can also froth non-dairy milks, but the results will vary. Some companies make “Barista Blends” of their non-dairy milks. These milks are specially fortified so that they froth better. One popular version is Califia Farms’ Barista Blend Almond Milk.
Instructions: How to Froth Milk with a Mason Jar
1. Prep: Pour 6 oz (3/4 c. or 175 ml) of cold milk into the mason jar
2. Heat: Put the jar of milk in the microwave (with the lid off) and heat until it is 150-155° F/65°-68° C, about 1 minute
- The ideal temperature for frothed milk is a matter of personal taste; anything between 140°-160° F/60°-70° C will work. However, milk scalds at 160° F/70° C—so if you overheat the milk it is ruined. At the same time, milk that is colder than 140° F/60° C will not froth properly.
- DO NOT microwave the thermometer. Remove the milk form the microwave to test the temperature.
3. Froth: Remove the jar from the microwave, screw on the lid, and then give it a good shake (for about 1 minute)
- The jar will be hot, so use oven mitts or a cloth to hold it while shaking
That’s it! You now have frothed milk!
