Grate potatoes through the large holes of a box grater (if you have a spiralizer, you can also turn them into thin noodles).
Stir together potatoes and flour. Stir in eggs, green onions and salt.
Pour oil to depth of 1/2 inch into a large heavy skillet, heat to 350.
Shape a generous tablespoon of sweet potato mixture into a patty and fry in batches, 2-3 minutes on each side. Drain on paper towels.
Makes about 2 dozen, and you definitely want to eat these immediately while they are still warm and crunchy.
Horseradish Sour Cream
Stir together ingredients in a small bowl. Cover and chill at least 30 minutes.
Spiced Thyme Applesauce
Stir together all ingredients in a saucepan. Bring to a boil over medium-high heat. Reduce heat to low and simmer for 5-7 minutes until pear is tender. A chunky applesauce is recommended but I used my regular applesauce and it was fine. I also omitted the ginger because I didn't have any on hand and we still wolfed it down.
To serve, I like to lay out the latkes and sides on a table and let everyone make their own. You can also put them together ahead of time and serve them like little finger-food appetizers. Either way, they're delicious!
