Incorrectly dicing your potatoes

Once you've chosen your potatoes and placed them on the counter, it's time to begin peeling and dicing. And you're not alone if your knife skills are lacking. As dicing potatoes can be a tricky task, take your time so you don't cut yourself. But, while you're dicing, make sure you're cutting the potato into even pieces. If you don't, different pieces of potato will cook at different rates. You don't want some of your potatoes to become mushy while the others have only just begun to cook on the inside, so keep this in mind.

Remember, the smaller you dice your potatoes, the faster they'll cook — just make sure they're all roughly the same size before you put them in the water. Plus, you won't have to do any more cutting once the potatoes are cooked.
