What are tater tots?

If you are in the United States you are probably familiar with what tater tots are, but other regions have asked me many questions about tater tots.

• Tater tots are a potato product that is crunchy on the outside and tender on the inside. They are made from grated potato that is shredded and formed into a cylinder shape and deep fried.
• In the UK, tater tots may be called Potato Crunchies or Mini Hashbrowns.
• In Canada, you may find them labeled as Spud puppies or Tasti Taters.
• In Australia or New Zealand, they may be called Potato Gems or Potato Royals.

Regardless of where you’re from or what you call them, they are absolutely delicious and the highlight of any tater tot casserole recipe.
