Hi George,
Since I don't work by recipe let me try this.
EVOO saute sausage to flavor oil then I add onions, usually around a half onion. Saute til soft, add tomato mixture - premade or your favorite saute, add salt and saffron and smokey paprika if you have it. Let thicken a little then add stock based on the amount of rice and size of pan, I only had veg but would usually go for seafood with seafood but it doesn't make much difference.
I just keep adding until I get the flavor, texture and smell that I want. Keep tasting the broth since that's what the rice will taste like =)
When you get a rolling type boil Add Arborio or Bomba rice see instructions on box vs liquid based on the size paella pan you are using.
I usually add the water to the pan in the kitchen even before i start cooking to the rivet area in my pan and leaving enough room from the top so it doesnt overflow so I know how much stock i will need when I start cooking. I do this so i know what im in for liquid to water to pan size. Ii have overflowed a few and it's a huge mess .
Timing the ingredients is key, shellfish take longer than shrimp and squid need to be sauted early in my opinion, salmon chunks are nice too. Just have to gauge the time for the rice and work around that.
Once the crusty bubbles are going and most of the water is has been absorbed I'll pull it and let it set up for about 3-5 minutes.
You can arrange the food as art on the top and expect it to look like that if you don't stir things. I tried to do the Spanish flag from red and yellow peppers on top but the light was a bit low.
On a side note watch this video, this is an old timer paella cook, watch the steps and just copy with what you have. It's really just the method of steps. I miss this show. I hope this helped.
Check the 14 minute mark.
