Peel apples one at a time and immediately grate each into a clean kitchen towel. Repeat until all 8 apples are grated.
Gather the kitchen towel around your apple pieces and form into a ball over the sink. Squeeze until there is little liquid remaining.
Transfer apple pieces to a large bowl and combine with the lemon juice, salt, cornstarch and AP flour.
Add cinnamon, ginger, nutmeg, and sugar and stir to combine.
Scoop latke batter into 10 large balls using an ice cream scoop. Gently sculpt each of them into a puck shape, about 1 1/2” thick.
Heat frying oil in a large skillet over medium-high heat. When oil reaches 350°F, add 4-5 latkes, making sure to now overcrowd the pan.
Cook for 2-3 minutes on the first side, until dark golden brown. Dark caramelization is normal due to the sugar.
Flip and cook for another 2-3 minutes and transfer to a paper towel-lined baking sheet.
Let cool slightly and dust with powdered sugar. Serve plain or with applesauce, sour cream, or whipped cream.
