Place the flour and salt in the bowl of a food processor fitted with a metal blade. Pulse 2 to 3 ties to combine.
In a medium bowl, whisk the eggs and olive oil until well blended. Pour egg mixture into the bowl of the food processor. Pulse 10 times or so to blend the egg mixture and flour together. Steadily process the mixture for a few seconds at the end if needed. If the mixture is too dry, sprinkle water in while pulsing a few more times.
Turn the mixture out onto a well-floured surface. Knead to bring together and smooth the dough out. Place the dough in a bowl with a cloth bowl cover and let rest for at least 30 minutes or tightly wrap the dough in plastic wrap and place in the fridge for up to 1 to 2 days.
Roasted Carrot Puree
Adjust oven racks so that one is on the top third level and the other is on the bottom third level. Preheat the oven to 400 degrees F.
Cut the carrots in half lengthwise and divide between two sheet pans. Drizzle the oil over the carrots and sprinkle with salt, and pepper. Toss well and arrange the carrots on each pan into one layer.
Place the carrots in the oven and roast for 25 to 30 minutes, until tender and starting to brown.
Remove the carrots from the oven and set aside to cool. Once cool, transfer the carrots into the bowl of a food processor fitted with a metal blade. Add the goat cheese and blend until smooth.
Purée can be stored in an airtight container in the fridge until ready to use as a filling. It can be stored in the fridge for up to 4 days or frozen for future use. Place in fridge overnight to thaw filling if you freeze it.
For Ravioli
Make an egg wash by beating the egg in a small bowl with 1 tablespoon of water. Set aside.
Working with 1/4 at a time, roll the pasta to desired thickness, then cut the pasta sheets into 4 ½-inch strips about 12-inches long.
Place 1 teaspoon of filling on the pasta sheet, leaving about 1 ½-inches between each. Using a pastry brush or basting brush, brush the egg wash around the filling. Fold the top half of the pasta over the bottom, pressing out any air pockets. Using a pizza cutter or ravioli cutting wheel, cut out the ravioli and place on a well floured sheet pan. Toss the ravioli to lightly coat in flour to avoid sticking. Repeat with the remaining pasta and filling.
Bring a large pot of generously salted water to a boil. Working in batches, cook the ravioli for 2 minutes, then, using a slotted spoon or spider, transfer to a colander set over a bowl. While hot, toss the drained ravioli with sauce that it will be served in. Be sure the sauce is warmed.
Make the dough: Put flour in a large mixing bowl. Stir together 1 cup water, 1 teaspoon salt and 4 tablespoons oil, then pour over flour and mix until dough comes together in a rough ball.
Turn out onto a floured board and knead until smooth, 2 to 3 minutes, adding more flour if dough is sticky. Wrap and set aside at room temperature for 30 minutes. (May refrigerate overnight and bring to room temperature.)
Make the filling
Heat 2 tablespoons oil in a large skillet or wide pot over medium heat. Add onions and a little salt and cook, stirring, until softened, about 5 minutes. Add greens, season generously with salt and pepper, and mix well.
Coarsely chop greens, add to mixture and cook until just beginning to wilt. Turn off heat.
Add nutmeg, ricotta and half the Parmesan and mix. Taste and adjust; it should be highly seasoned. Beat 4 of the eggs. Set aside 3 tablespoons beaten egg; add remaining beaten egg to greens and mix well. Let cool.
Heat oven to 375 degrees. Cut dough into 4 pieces and form into balls. Roll out each ball into a very thin 12-inch circle. Place 1 dough circle on a 12-inch pizza pan lined with parchment. Brush lightly with oil, then lay another dough circle on top.
Spoon greens evenly over dough to a 2-inch thickness, leaving a 1-inch border of dough. Smooth the surface. With a soup spoon, make 5 indentations in greens and crack a raw egg into each depression. Sprinkle with remaining Parmesan.
Cover with another dough circle and paint lightly with oil. Place last dough circle on top. Using a paring knife, trim any excess dough at perimeter of pie. Fold outer edges together and crimp to seal pie. Paint top with reserved beaten egg. Using a paring knife, make 2 or 3 steam vents.
Bake for about 45 minutes, until very well browned. Slide torta onto a cutting board and let cool slightly before slicing. May also be served at room temperature.
Place oven racks at the upper and lower thirds positions and preheat oven to 250 F.
Coarsely grate celery root into a bowl using the 1/3 inch-wide holes of a box grater.
Peel potatoes and coarsely grate into a large bowl. Add lemon juice and toss. Coarsely grate onions into the same bowl.
Transfer to towel, then gather the corners to form a sack. Twist tightly to wring out as much liquid as possible.
Return potatoes and onions into a clean bowl and stir in celery root, flour, eggs, salt, pepper and celery seeds until well combined.
Heat 1/3 inch of oil in a 12-inch nonstick skillet over moderately high heat until hot, but not smoking. Fill a ¼ cup measure (but do not tightly pack) with the latke mixture and carefully spoon into the heated skillet, then fry until the underside is a deep golden color (1 ½ to 3 minutes).
Turn over using 2 spatulas and fry until deep golden on all sides (1 ½ to 3 more minutes).
Transfer to paper towels to drain briefly. Keep warm in a baking dish in the oven.
Repeat frying process until all latkes are cooked.
Recipe Notes
Helpful Hints:
You may fry latkes 1 hour ahead of serving time.
You may shred the potatoes, onions and celery root in a food processer with the shredding disk.
However use 5 eggs (instead of 4), as the machine will grate more coarsely than hand grating and will require more binding.
Monitor the rate at which the latkes brown. If they brown very quickly, try reducing the heat to
moderate.
