Drive south from Valencia and the city gives way to water. The Albufera is a shallow freshwater lagoon, the largest lake in Spain, held back from the sea by a spit of pine and dune. Around it lie the rice paddies, flooded and mirror-flat in spring, gold and stubbled by autumn. This is where the dish begins, not in a restaurant but in a field, and it is worth remembering that before you order.
Rice arrived here with Al-Andalus, planted in the wet ground below the city more than a thousand years ago. Paella came later and lower down the social order. It was a labourers' lunch, cooked over a fire of orange and vine cuttings, eaten from the pan with a wooden spoon while the sun was high. The word paella is simply the pan itself. Everything about the dish still points back to that open flame in the middle of the day.
The orthodoxy is strict and the Valencians will tell you so. Bomba or Senia rice, grown in the same water you can see from the table. Chicken and rabbit. Flat green ferradura beans and the big white garrofó. Tomato, sweet paprika, saffron, good oil, and the water. Snails when they are in season, a sprig of rosemary if the cook feels like it. That is the canon. No chorizo. No peas, no seafood, no yellow food dye standing in for saffron. What arrives red with sausage on the tourist strip near the beach is another dish wearing the name.
It has ten ingredients and a thousand arguments, and almost every argument is about what to leave out.
The part worth waiting for is the bottom. As the last of the stock cooks away the rice meets the hot metal and toasts, and that thin caramelised crust is the socarrat. Valencian families quarrel over it, gently, the way families quarrel over the good end of the roast. A cook who cannot raise a socarrat is politely not asked again.
Eat it at El Palmar, the fishing village set among the paddies, where the pans come to the table wide and shallow and nobody stacks the rice into a dome. Go at noon, as it was meant to be eaten, and take a boat out on the lagoon afterwards while it settles. The paella you will be served everywhere else in Spain is a fine thing. This is the one with a birthplace, and it is close enough to see.
