Bitterness usually comes from chemical compounds called alkaloids or glucosinolates. Think of them as the plant’s bodyguards—they’re there to warn off predators. You find them in leafy greens, eggplants, coffee, and even some spices. But here’s the irony: these same compounds are often packed with antioxidants. So you don’t want to nuke them out of existence, just balance them.
Heat, age, and growing conditions can make bitterness worse. An old cucumber? Bitter. An overripe or under-cooked eggplant? Bitter. A burnt garlic clove? Unforgivably bitter. So step one is diagnosis: is your ingredient fresh? Did you just char it to hell? (We’ve all been there—no judgment. Just turn on the fan and move on.)
