Q: I love going to little coffee shops to get a latte during my lunch break. I don’t drink all of it, but sadly around the 4 o’clock slump in my office, it is cold and gross. Is there a way I can reheat my latte, so it is just as good?
A: Reheating milk based beverages is not recommended because of separation, curdling, and becoming very sour. However, if you were to make your own latte at home, there are several ways you can do it!
The Stovetop Method
For the most part, using the stovetop will just require a bit of stirring. First, you will want to add the amount of coffee desired, be sure not to add too much, as you should not reheat the leftovers. After you have the coffee in the pot, begin to warm it over medium-low heat. After several minutes, and your coffee is just beginning to warm, add the amount of milk (and sugar) you would like at this point.
It is very important you do not let the mixture boil! Not only will it become bitter, it may boil over causing a mess of curdled milk!
The Microwave Method
The microwave is not recommended to warm coffee as it may become quite bitter. However, if you are already adding sugar and creamer, then it may not be an issue for you. To make a microwave latte, simply add your coffee to a microwave-safe mug, and microwave in 30-second increments until warm. After it is at the desired temperature, add your milk and sugar and stir well.
While you may not get the frothy drink that your coffee shop provides, being able to make and reheat your own latte at home is just as important. So sadly, no you should not reheat your latte because nothing is worse than getting sick, and still having to be in the office for a few more hours.
