Grab a medium-sized russet or Maris Piper. Too big and it takes forever. Too small and you’re hungry again in ten minutes.
Give it a good scrub. You’re eating the skin, so please don’t skip this step.
Now, pierce it. Like, stab it a bunch of times with a fork. It’s not revenge; it’s science. Steam needs to escape, or you’ll hear a mini-explosion in your microwave.
Trust me. Cleanup is not fun.
