Heat your olive oil in a large deep skillet or paella pan over medium-high heat. Once it's shimmering—when you can see the oil literally moving around the pan—add your chicken chunks in a SINGLE LAYER. This is CRITICAL. If you crowd the pan, you'll steam instead of sear. Let the chicken sit undisturbed for 3-4 minutes on each side until you see golden-brown color developing. You're not cooking it through—just developing flavor through browning (what chefs call the Maillard reaction). Once both sides have color, transfer to a clean plate. The chicken will finish cooking later, so slight undercooking now is PERFECT. Pro tip for entertaining: You can brown your chicken up to 4 hours ahead, cover it, and refrigerate. This removes stress on cooking day and lets you focus on the final assembly.

Reduce heat to medium (this is important—LOW, not high). Add your sliced onions to the same pan with all those browned bits stuck to the bottom (we call this fond, and it's LIQUID GOLD for flavor). Stir occasionally and let them cook slowly for about 10 minutes until completely softened and turning translucent at the edges. You're not rushing this step. Slow-cooked onions develop natural sweetness that balances the smokiness coming next. This is where patience pays dividends—RESIST the urge to turn up heat and hurry. After 10 minutes, add your crushed garlic and stir constantly for exactly 1 minute. Garlic burns quickly, and burnt garlic tastes bitter and acrid. One minute—that's it—then you move forward.

This is where things get EXCITING. Add your sliced chorizo to the pan and fry it over medium heat for 3-4 minutes, stirring occasionally. Watch as it releases its gorgeous reddish-orange oils into the pan—that's the smoke essence coating everything. This step is NON-NEGOTIABLE for authentic paella flavor. WARNING: Do not skip chorizo cooking. Raw chorizo tastes greasy and unfinished. Those 3-4 minutes transform it from ingredient to flavor foundation.

Add your turmeric, saffron threads, and smoked paprika directly to the pan. Stir constantly for about 30 seconds—you're blooming the spices in those hot oils, which intensifies their flavor dramatically. You'll smell that beautiful warm earthiness filling your kitchen. THAT'S how you know it's working. Now add your 300g paella rice. Stir for 2 full minutes, coating every grain in those golden, spice-infused oils. The rice should look glossy and slightly translucent. This toasting step is what separates paella from regular rice—it creates structural integrity so grains stay separate and firm instead of mushing together.

Pour in your 850ml hot stock (TEMPERATURE MATTERS—cold stock disrupts the cooking process and extends cooking time unpredictably). Stir once, then bring to a boil over medium-high heat. Once boiling, return your partially cooked chicken pieces to the pan. Do NOT stir anymore from this point forward—paella isn't risotto. You're not stirring constantly. Instead, you're letting the liquid absorb into the rice from the bottom while the top stays exposed to heat and steam. This creates the coveted crispy bottom layer (called socarrat) that makes paella so extraordinary. Reduce heat to medium and let it simmer gently for about 20 minutes. Liquid will gradually absorb, rice will soften, and chicken will finish cooking. You can stir occasionally if you're worried, but honestly? Patience serves you better here.

After 20 minutes, scatter your frozen peas across the top and stir them in gently. Simmer for another 5 minutes. The rice should be tender but still have a slight firmness (never mushy), the chicken should be cooked through and tender, and the peas should be bright green and heated through. Remove from heat. Taste and season generously with sea salt and freshly cracked black pepper. Everyone's stock salt level differs, so trust your palate here. CRITICAL DONENESS TEST: Taste a grain of rice. It should be tender but have a tiny bit of resistance when you bite down. Overcooked paella is mushy and sad. Undercooked is crunchy and wrong. That sweet spot takes practice, but you'll nail it.
