Every week -- often with your help -- Food52's Senior Editor Kristen Miglore is unearthing recipes that are nothing short of genius.

Today: Leftover mashed potatoes get a new lease on life -- and you get a morning-after Thanksgiving breakfast you'll actually want to cook (and eat).

Come Friday, you will have leftover mashed potatoes. 

Because you know that running out is the worst thing that can happen on Thursday, second only to dropping the pie on the floor.

But rewarmed mashed potatoes are never destined to be terribly good -- they turn floury and dry overnight, and any attempts to revive them only succeed in making them more sticky.

There are lots of places to secretly stick leftover mashed potatoes, but the question of seasoning complicates matters. Can you reuse that dreamy garlic buttermilk mash in your cinnamon rolls or chocolate cake or Spudnuts? No. No, you cannot.

And, honestly, are you ready to make anything of the sort the day after a Thanksgiving feast? (If you are: high-five for you.) Casual bread bakers might work their clumpy potato remnants into flatbreads or country loaves; I bet they've even saved the potato cooking water too. Good for them!

But for the rest of us, I wanted something simpler, something we'd actually be ready to cook on Thanksgiving, Day 2 -- something that could work with any family's mashed potato dregs, and make them feel new. I wanted something that would go really well with fried eggs.

I found it in Bert Greene's classic Greene on Greens: fritterra -- a leftover mashed potato cake like you've probably seen before, but with a few smart upgrades. (As a Thanksgivukkah bonus: these totally count as latkes.) "It was a gift from a taxi driver," Greene says in the recipe's headnote, "who related it in pieces -- each time we stopped for a light."

Upgrade 1. He uses a lot of scallions, but blanches them first -- a (quick) extra step that packs in fresh greenness without the bite and regret of raw alliums.

Pro tip: Be sure to chop the blanched scallions finely, or the cakes will break along scallion fault lines as they fry.

Upgrade 2. To bind the cakes, Greene uses a combination of egg and bread crumbs instead of flour, the latter of which can be a slippery slope and make cakes with the pasty chew of a pencil eraser. Breadcrumbs are much more forgiving.

Don't be shy with the heat. Searing them quickly helps hold the loose batter together -- this will allow you to not keep adding breadcrumbs, which after a certain point, you will regret.

If you're the kind of family that buzzes around cooking together all day on Thursday, here's your chance to do a little bit more -- but unlike Thursday, where you'll spend all day smelling turkey and being asked to wait, these cakes come together in minutes. You won't be able to eat them fast enough.

Skipped the blanching step since I was short on time and didn't miss it. And while it seems like a crazy amount of scallions, that's really the trick; use more than you think is wise and get really flavorful pancakes. A great way to use up odds and ends, and transform one thing into something else, especially if leftovers have limited appeal after the first time or two you have them.

I grew up on these too, and we almost liked them better than the mashed potatoes! Mom always used grated onion instead of scallions. Now I make them all the time for my kids.

Thanks for the grated onion tip!. I used a large sweet onion and some chives from my garden for color - delish!

While these sound yummy I'm trying to figure out how 1.5 cups of mashed spuds, 12 scallions and 2 eggs equals 4 servings. Sounds like a tease to me. Small servings just make me cranky.

Looks great-- and I think adding some fresh or frozen corn would be a nice addition too.

As long as you are using "leftovers" from Thanksgiving.....why not use leftover stuffing in place of the breadcrumbs

Love that idea.

Gosh these look amazing! Like a luxury hash brown! Yum!

I make them for breakfast and put whatever leftover meat from the day before in them too - chopped up grilled lamb and chopped slow roasted pork butt are family favorites. You can also put a little sour cream in the mix if the potatoes are too dry.

Grow up eating this. Mom fixed all the time. She just used regular onions.

Grew up eating potato cakes with fried eggs, but never like these. Plan to make some mashed potatoes just so I can have this for Friday breakfast! And agreed that Bert Greene was an unsung genius. Love his books

Here's my take: mix leftover potatoes with shredded cheddar, spices of your choice, a little milk to bind. Form cakes; dip in beaten egg, then panko. Place on lightly oiled cookie sheet, spray with olive oil. Bake at 400 degrees or so for about 20 minutes per side (or until nicely browned). Always gets raves...

We're having real latkes tomorrow, so this deliciousness will have to wait a few days. You've also reminded me to fritter my leftover quinoa with green onions, garlic, and parmesan. Absolutely amazing with sunnysides! (Oh, and more eggs to hold the quinoa patties together!) YUMMY!

I love that you found this in an old Bert Greene Cookbook! He is a name more people should know.
