The "Shad Bake" appears to be a New England phenomenon that occurs in small towns along the Long Island Sound and Atlantic coast where shad (a species of fish) migrate from the saltwater up into freshwater rivers for spawning (more on their life cycle) . Actually shad bakes may occur in other areas like the Chesapeake Bay area or whatnot, but my knowledge of the gig is from witnessing the Shad Bake of the Rotary Club of Essex, CT.
I have never actually cooked shad. I just took pictures and asked questions. So if you know more, please leave a comment and I will fill in the gaps as we go.
Step 1: Procure Shad
I know very little about this step. My guess is that it goes like this: You know a guy. The guy catches shad. You put in an order prior to the Shad Season. The guys catches the shad with gill nets. You pickup shad and bone them (which I hear is a challenge). Or you pay the guy more to bone them. Either way, here is what the shad will look like when you are done boning.
Obviously we need and instructable on catching and prepping shad. Somebody step up.
Step 2: Procure/Build Other Stuff You Will Need
1) Boards for cooking
2) pork fat strips
3) hammers, nails, spatulas
4) food thermometer or knowlege of how long to cook the fish
5) some sort of rub (a la Old Bay or whatever the local Guy says is good on the fish)
6) hardwood scraps for the fire
7) side dishes
Step 3: Attach Fish to Boards and Start Fire
Start by laying out the fish on the boards so that there is about 3-4" between the cuts. Lay the pork strips accross the top and bottom of the fish. The pork does two things: it flavors the fish and helps hold it together. According to the Rotary folks, once the fish has been de-boned, it tends to fall apart so the pork helps keep everything together. Also, it tastes good.
Tap a roofing nail into each end of the pork (4 nails per fish). Don't drive the nails in too far - just enough to hold the fish as it cooks.
Also, they may soak the boards in water to keep them from burning - but I think once they are used enough they just because one with the fish.
Step 4: Set Up the Boards for Cooking
Each board has a prop stand that keeps it almost vertical in front of the fire. The Rotary folks use a little dripping tray under each one so that they don't leave a mess at the elementary school. This would not be required. Once you have a good bed of coals, set the shad around the fire in a circle or semi circle depending on how much fish you have. If you have a lot, the fire will be in a ring, with few to no coals in the middle. Although they probably started the coals in one center fire and then raked them out. The key here is to have enough coals in front of the fish to cook it indirectly. If the fire is hot enough that you cant keep your hand near the fish for longer than a few seconds it's probably hot enough.
Once the boards are set up, have a beer and get ready to serve the fish. This is also a good time for some raw clams or mussels or some such.
Step 5: Cook the Fish and Listen to the Brass Band
I don't have hard data on cooking times, and it depends on how hot the fire is. I'm guessing each rack takes 20-40 minutes depending on these factors. I would have an instant-read food themometer on hand and take the fish off when they are at a safe eating temp (which is probably higher than the local Guy would recommend - most food can be eaten safely and at a lower temp and tastes better as a result. But I take no responsibility for your food safety practices or contaminant content of your fish. Please do your own research and use logic).
Flip the board top for bottom half way through the cooking process. This is because the fish on the bottom do not get as much indirect heat....
The fish that came off of the racks in Essex had a nice brown crust - some were more done than others. All were excellent.
While the fish are cooking, enjoy the brass band that you invited to attend (did I mention the brass band in the ingredients section?).
Step 6: Remove Fish From Fire and Pull Nails
This is a video of the nail pulling process. It seems to be important that the guy with the board yells "BOOAARRRDD!!!" as he approaches so that the other guys can put down their beers and get ready to pull nails. Yelling makes everything taste better - kind of like salt.
Step 7: Serve and Eat
The Rotary club serves the fish with a white potato salad, a green salad with Italian dressing and a slice of apple pie with a slice of cheddar cheese on top.
Eat the fish and go back for seconds and thirds.
