  1. Thank you for the fascinating facts. I used to love having sweet potatoes on holidays in the states. Here in Latvia, they are not popular so it will be a treat to have them when I get back to the states.

    • A big selling item at the store is sweet potato fries. I like them candied like you mentioned; baked with brown sugar and butter, and we usually put marshmallows over the top. That’s a dish we have on Thanksgiving and Christmas.
