You got less than four hours of sleep last night and you’ve got a huge day at work ahead of you. Thank goodness for…BITTER COFFEE (said no one, ever).
Sipping particularly bitter joe is a major disappointment, but the day must go on. Luckily, there’s a way to revive your cup in a pinch (of salt).
What you need: Coffee and salt.
What you do: Add the salt to the offending coffee and stir.
Why it works: Salt weirdly bonds to the parts of your taste buds that detect bitterness and stops them from properly doing their job. Science!
The end result: You might be able to notice a faint taste of salt, but if you prefer sodium to bitterness, this trick’s for you.
