1. 1
   Wash the tomatoes, remove the cores and quarter each tomato.

2. 2
   Put the tomatoes, the salt and half of the olive oil in a wide pot, cover and cook over medium heat about 20 minutes, until the tomatoes soften and release their liquid.

3. 3
   Pass the tomatoes and their liquid through a food mill or sieve and return the purée to the pot: the skins and seeds stay behind.

   Cook uncovered about an hour at a lively simmer, stirring now and then, until the purée reduces by half.

   💡The paste burns easily as it dries: stir and scrape the bottom and edges, and once it is thick, don't walk away.
5. 5
   Preheat the oven to 110°C (230°F).

   Oven

   💡Put things in the oven only once it's reached temperature, after the heating light has gone off: an oven that hasn't reached temperature changes baking times, and the bake burns outside or stays underbaked.
6. 6
   Grease a wide baking dish with the rest of the olive oil and pour in the purée in a thin layer. Dry in the oven about 3 hours, stirring and scraping the edges every 30 minutes, until the paste is thick, sticky and brick red.

For the Fried onion

1. 8
   Heat the olive oil in a wide pan over medium heat.

   StoveFrying pan
2. 9
   Add the onion and fry 5 minutes, stirring now and then, until the onion is soft and translucent and starts to turn golden at the edges. If it browns too fast, lower the heat.

   Stove

   💡Add by cooking time: what needs long (onion, carrot, meat) goes in first, and what burns fast (garlic, dry spices) goes in last, only until fragrant.
3. 10
   Add the garlic and fry about 30 seconds to 1 minute, just until fragrant. Don't let the garlic brown.

   Stove

   💡Garlic burns quickly and turns bitter. Add it only after the onion has softened, over medium heat, and add the next ingredient as soon as it smells fragrant.
4. 11
   Add the peppers and fry about 3 minutes, stirring, until they soften.

   Stove

To assemble

1. 12
   Soak the dried peppers 30 minutes in hot water, drain and remove the seeds.

   Bowl
2. 13
   Grind the peppers in a food processor with the garlic, salt and black pepper.

   Food processor

   💡In a food processor, grind in short pulses and check between pulses: it's easy to go from coarse to paste. (Sesame for tahini, on the other hand, is ground continuously.)
3. 14
   Add the oil in a thin stream, while Tahini, until a smooth paste.

   Food processor

   💡The thin stream is everything: fat that goes in too fast can't bind, and the sauce breaks. For mayonnaise and hollandaise, if this happens, start with a fresh yolk and slowly add the broken sauce to it; if the sauce is too thick, thin it with a teaspoon of water.
4. 15
   Add the tomato paste, chili, cumin and turmeric and stir for a minute, until fragrant.
5. 16
   Add the tomatoes and season with salt and black pepper. Turn down the heat and simmer for 15 minutes, until the sauce thickens.

   Stove

   💡The sauce is ready for the eggs when a spoon dragged across the bottom of the pan leaves a trail. A sauce that's too thin cooks the eggs in water, not in sauce.

   💡A gentle simmer, not a boil: a hard boil dries the food out and clouds it, a slow simmer cooks it evenly.
6. 17
   Make wells in the Dressing and crack an egg into each one. Cover and cook 5–7 minutes, until the whites are set and the yolks are still runny.

   StoveLid

   💡Crack each egg into a small cup first and slide it into the well: that way the yolk doesn't break, and a stray bit of shell is easy to remove.
7. 18
   Sprinkle the cilantro on top and serve immediately with fresh bread for dipping in the sauce.
