Here's mine:
Fresh corn on the cob
Fresh shrimp ( not the Walmart kind)
Fresh clams (see above)
Sausage ( your taste preference)
Small red potatoes (wash and leave skin on)
Chicken (optional for non seafood lovers)
Crab legs (or whole blue crabs if you can find them)
Old bay seasoning
I start the process with the potatoes, sausage, and corn (chicken as well if you desire)
I add seafood or clam broth as well as chicken broth.
Add old bay seasoning. You have to be careful with this. Too little means too bland. Too much and people may not be able to eat it. I always taste the water and add accordingly.
Once those items are near finished, add clams and crabs. Shrimp should go in last. Add 2 cups of vinegar to help with peeling the shrimp and cleaning the crabs. The seafood portion should not take very long. Shrimp is done when pink.
I like to bag each item separately to make easier to serve. If you have no bags, drain pot and put in separate containers to make serving easier. This is easy for me to find ingredients since I live at the coast.
You can add things like onions and celery, but I find they do not help with the flavor. The sausage, seafood, and old bay are the dominate flavors. People who have a shellfish allergy cannot eat any part of this meal
