I found this on Foodnetwork.com. Great recipe!
How do you know when the rice in a multi-component rice dish has reached the exact midpoint between resistance and mushiness? That precise moment relies entirely on visual inspection of the grain surface rather than strict adherence to a kitchen timer. Short-grain varieties absorb liquids differently based on pan width and heat distribution, requiring the cook to monitor moisture absorption closely through the transparent simmer phase.
Achieving proper texture requires understanding that proteins and starches cook at divergent rates when combined in a single vessel. While pork and poultry need initial browning to develop Maillard compounds, delicate seafood like shrimp and squid added later will toughen permanently if subjected to excessive heat. Managing this timeline means browning the meats thoroughly at medium-high heat before introducing aromatics and liquids.
Substituting Calasparra or Bomba rice for standard short-grain varieties changes the liquid absorption ratio significantly, often requiring an extra two to three ounces of stock per ten ounces of grain. Always allow the finished dish to rest uncovered for five minutes after baking at 350 degrees Fahrenheit to let the starches set and form the characteristic bottom crust known as socarrat.
