Squash contains a compound called cucurbitacin, which in large doses can make it taste intensely bitter—and sometimes mildly toxic. Blanching can reduce that bitterness by leaching some of the compound into the water. So you’re not just cooking smarter; you’re actively saving yourself from a bitter, slightly gastrointestinal crisis. You’re a hero.
So go forth. Boil a pot. Shock a squash. Feel like a kitchen wizard who knows the secret handshake. And when someone asks, “How do you blanch squash?” you can say, “Quickly, with ice, and a dash of existential vegetable humor.”
Now excuse me, I have to rescue a zucchini from my overly aggressive ice bath. It’s been in there four minutes and I think it’s giving me the cold shoulder.
