Eggs in purgatory
Neapolitan: the eggs set inside a spicy tomato sauce, unbeaten and with no second pan. The spinach goes into the sauce before the eggs and makes the bed. Twenty-seven minutes and a single skillet.

Why this one and not another
Except for the spinach, all of it comes out of the pantry —can, eggs, onion, garlic—, so it's the dish in this batch you can cook without having gone to the store. Twenty-seven minutes and a single skillet. The second portion reheats with no trouble, with the warning that the yolks are not going to wobble anymore.
Where it comes from
Uova in purgatorio is Neapolitan: the eggs set inside a spicy tomato sauce, unbeaten and with no second pan, and the name always gets explained the same way, by the yolks peeking out of the red. The move —setting an egg inside a sauce that was already made— shows up in half a dozen kitchens, and in Naples you eat it with bread to drag through what's left. Here there is no bread and what picks up the sauce is the spinach, which goes inside and not underneath. That swap has a cost the recipe pays with a step: you have to wait one more minute for the sauce to thicken again after the leaf gives up its water.

2Steps
In this order. The box on each step is the specific pitfall: what goes wrong there and why.
- 1
Sweat the onion, then the garlic
5 minOil over medium heat, the onion until it turns translucent, and only then the garlic slices and the pepper flakes, half a minute.

- 2
The crushed tomato, until it thickens
10 minMedium heat, uncovered, stirring now and then and scraping the bottom. Salt.

- 3
Add the spinach and let it give up its water
2 minAll of it at once; it collapses in a minute. Stay on medium heat until the sauce thickens again.

- 4
Make four wells and crack the eggs into a cup
3 minWith the back of the spoon, four separate nests. Crack each egg into a cup and slide it from there into the well.
- 5
Cover, low heat, until the white sets
6 minFive or six minutes. Shake the pan: the white no longer moves, the yolk does.

- 6
Torn basil and parmesan off the heat
1 minThe leaves torn by hand over the top, the grated cheese and raw olive oil. Pepper.

3If something goes wrong
- The whites fell apart into threads
Why: The sauce was watery, or boiling hard when the eggs went in.
What to do: Thicken the sauce until the spoon leaves a track, drop the heat to its lowest and cover.
- The yolks came out hard
Why: You waited until they looked firm from above.
What to do: Pull them when the yolk still wobbles as you shake the pan. It finishes setting on its own on the way to the table.
- The sauce tastes of raw, sharp tomato
Why: The ten minutes weren't served, or it was covered and nothing evaporated.
What to do: Uncovered and over medium until it darkens and pulls away from the bottom. Time is the only ingredient it's missing.
