To keep your coffee hot for as long as possible, should you add cream right away or wait until just before you drink it? Will the addition of cream make coffee cool faster or slower?
The Modernist Cuisine team sought to answer these important questions. It turns out that coffee with cream added actually cools about 20% more slowly than plain black coffee, so it is best to add the cream immediately. But why is this?
A sidebar in Modernist Cuisine reveals the three major principles of physics that determine why coffee with cream cools more slowly. Check out the high-speed videos below and see if you can guess these three factors!
