A very traditional potato latke / potato pancake recipe even your mother would love

My mom and I had a few traditions: lunchtime wine at the Olive Garden, margaritas at El Paso Café, a Beefeater gin on her birthday, a really nice medium Filet Mignon at Outback, and lunches at Jewish delis. We would always start with a plate of potato pancakes--latkes--with sour cream and apple sauce. We would follow-up with corned beef on rye with mustard but I always look forward to snacking on well-made, traditionally-fried, crispy potato latkes. I'm more of a sour cream guy but I do like a good apple sauce. 

Note: I am currently on a keto diet -- a ketogenic diet -- and as I pursue ketosis, I think I am getting super-nostalgic for traditionally-delicious, though high-carb, comfort foods like potato pancakes -- potato latkes -- and my savoury crêpes. So, please indulge me!
