Instead of paying big bucks for a milk steamer or a store-bought latte, you can make your own in a few minutes with just a milk frother, which costs less than $20. Pour some milk and sugar into your mug and then microwave it for a bit, then use your frother to make the mixture foamy. Then just pour in your coffee and enjoy.
Cold-brewing your own coffee is both easy and cheap, and it offers a much different taste (less acidic) than hot-brewed coffee. To do it, soak ground coffee beans in water for 12 hours (overnight), and then strain out the grounds. Now you can either pour this coffee over ice and add cream and sweetener, or you can heat it up if you like it hot.
