This is a wonderful dish for entertaining. The presentation is fabulous, but it is still a one-dish meal. All of the time involved is prep time. Once it's in the pan, you are free to mingle with your guests while it cooks. This is a pricey dish to prepare, but you can control the cost somewhat by using less expensive ingredients. The chorizo, chicken and shrimp are mandatory. The rest is up to you. A note about the chorizo - don't use Mexican chorizo, it is a completely different product and doesn't work in this dish. If you cannot find Spanish chorizo sausage, use spicy Italian sausage instead. It's not the same, but it will give a good flavor. Also, the very best rice to use for this dish is Bomba rice from Spain. You can find it at stores that import food products from Spain or at on-line sites. If you can't get Bomba, use Valencia rice. Since this is a rice-based dish, look for the best rice for complete success. Italian arborio is not a good choice, nor is long grain, short grain or Basmati. Plan ahead and find the sources you need for the right ingredients. This comes out best if you use a very large shallow pan that has a cover. I use a 16" non-stick pan with sides that are about 3 1/2 inches high. You can find these pans in some Chinese markets at a very low price. Some of those large covered chicken fryers can work too. Otherwise, use two pans and divide everything between the two pans. Everyone I have served this to talks about it years later. It is that good!
