For the tomato stock: Heat the oil in a stockpot over medium-high heat. Saute the carrots, celery and onions. Stir in the ketchup, peppercorns, tomatoes and garlic. Add the basil, parsley and enough water to cover. Simmer over low heat for about 45 minutes. Strain.
For the roasted tomatoes: Preheat the oven to 350 degrees F (180 degrees C). Arrange the tomatoes on a baking sheet lined with parchment paper. Drizzle with the oil, add the thyme and season with salt and pepper. Bake for 45 minutes. Let cool.
For the zucchini: Heat the oil in a saucepan over medium-high heat. Saute the zucchini and shallots for about 2 minutes. Season with salt and pepper. Add 1 cup (250ml) tomato stock and continue cooking for about 2 minutes. Stir in the butter, and then the chives and parsley.
For the latkes: Coarsely grate the potatoes into a large bowl of cold water. Drain. Spread the potatoes and onions on a kitchen towel and roll up. Twist the towel tightly to wring out as much liquid as possible. Transfer the potato mixture to a bowl and stir in the chives, eggs, cayenne and some salt and pepper. Shape the potato mixture into patties.
Heat the canola oil in an ovenproof nonstick skillet over medium-high heat until hot but not smoking. Working in batches, if necessary, cook the latkes until golden brown, about 2 minutes per side. Transfer the skillet to the oven and cook for about 5 minutes.
Serve the latkes with a scoop of ricotta, the roasted tomatoes, zucchini and fried eggs.
