Cucumber

Listen, a cucumber is mostly water, and that's exactly why it behaves the way it does in your hands. Water fills the flesh, stretches the skin tight, and gives you that snap when you bite. Once a cucumber starts losing water, the flesh goes soft and bends instead of breaking. So choose by that snap. Hold it, flex it slightly — it should feel firm, almost stiff, not rubbery. The skin should be tight and glossy, no wrinkles near the ends, no soft spots when you press with a thumb. Check the ends closely — if they're shriveled or give under light pressure, the cucumber has been sitting too long. A good one stays firm right to the tip.

Now, some people say a bitter cucumber means it's spoiled or dangerous. No! Bitterness lives mostly near the skin and the stem end, especially in older varieties, and it has nothing to do with spoilage. That misconception leads to a real mistake in the kitchen — people throw away good cucumbers, or worse, peel off all the skin to be safe, losing the crunch and the color for nothing. Just taste the tip, cut it off if it's bitter, and use the rest without fear.
