Pepitas are actually a part of regular pumpkin seeds. They’re the small green seed that lives inside the white shell of a pumpkin seed. A big difference between the two is that you have to roast regular pumpkin seeds before eating them whereas you can eat raw pepitas without roasting them. It can be a pain to shell pumpkin seeds so it’s best to just buy these from the grocery store where they’re already done for you. If you’re into growing your own pumpkins, you can also find a specific variety of pumpkin that will only produce the pepita and not the whole shell.
