Preheat oven to 200 degrees F (95 degrees C) for keeping latkes warm.
Peel potatoes and soak in a large bowl of cold water. Slice Potato (1.25 pound) in long chunks. Insert shredding blade into Food Processor.
Insert potato slices into tube of Food Processor and shred. Mix the Vitamin C Tablet (1) to shredded potatoes in a separate bowl.
Replace shredding blade with the main chopping blade. Place shredded potatoes back into Food Processor. Add in Onion (1) and Garlic (1 clove) to the Food Processor. Pulse several times until consistency is on the thick-side (like cottage cheese texture).
Then put Egg (1), Matzo Meal (1/4 cup), Kosher Salt (3/4 teaspoon) and Ground Black Pepper (to taste) in a large bowl with the potato/onion/garlic mixture. Mix it all together.
Pour about ¼ inch of Vegetable Oil (to taste) into the large frying pan(s). Heat on high for about a 1-2 minutes and lower as needed.
Add a large spoonful of batter into the pan in a mound shape and wait about 60 seconds. Press down gently with a spatula and flip over when the edges start to brown. Remove the latkes when cooked and place on a large sheet pan.
After you have fried all the Latkes, place in oven to stay warm and serve hot.
Top with Sour Cream (to taste). Serve and enjoy!
