Pick it up. Compare two squashes that are the same size. The heavier one is more ripe. Why? Because ripeness means the flesh is packed with moisture and sugar. A light squash is hollow, dried out, or still growing up.
It’s like comparing a wet sponge to a dry one. You want the wet, heavy sponge—that’s the one that will roast into buttery, caramelized bites. A light squash is a sad, stringy disappointment.
The Thump Trick (It’s Not Just for Watermelons)
Give it a gentle thump with your knuckle. A ripe butternut squash makes a dull, solid sound—almost like knocking on a wooden door. An unripe one sounds hollow and tinny, like knocking on a plastic bucket.
This isn’t magic; it’s physics. The dense flesh of a ripe squash absorbs sound. The airy interior of an unripe one bounces the sound back. So listen—your ears know what’s up.
