What are two things that are good on their own but bad when combined? And bad things that are good when combined? - Lemmy.world

I just learned about “Salt (NaCl) is actually a combination of a highly poisonous gas (Cl) and a hazardous metal (Na)”. I’m sure there are lots of examples in life that this rule also applies to.

Blue cheese and orange juice! It’s such a bad combo it’s worth trying.
is it sooo bad that it’s good? or something else
No, it’s just bad. Still worth testing. Kind of amazing how bad it can be. It can also be a practical joke to add to your bag.
i have another one like this: salty paprika chips and nutella!! i swear, puking it out was worth it 😂😂
That already smells like puke in my head!
