You’ve probably heard about pulling a leaf from the top. Honestly, it’s the least reliable trick, but it’s fun. Grab a leaf from the very center of the crown and give it a gentle tug. If it comes out easily and without much effort, the pineapple is likely ripe. If it resists, the fruit is probably still green.
Don’t go yanking out a fistful of leaves, though. You’ll make a mess and the produce guy will give you the side-eye. Just one polite little tug. Think of it as asking the pineapple a question: “Are you ready?” A leaf that pops right off is a quiet yes.
