I like the center cut salmon fillets that have part of the fin, (at least I think it's the fin?) It has one thicker side and tapers into a thinner side. I like the flavor of the fin. It definitely isn't the tail end.
Trader Joe's has great fresh salmon fillets in their fresh meat/seafood section at the side of the store. They are vacuum packed, but FRESH. The ones I like are called "bbq cut," style, pre-cut into 2-inch wide slices. You can throw the whole pack right in the freezer. Yet, I like to separate them, wrap them in plastic wrap separately. They freeze beautifully and can be pulled out one at a time as desired. Do NOT get the pre-frozen ones at TJ's. They just do NOT taste the same.
I also occasionally like a good salmon steak. It looks like a 1-1/2 inch thick horseshoe.
I prefer to steam the salmon in a parchment paper packet. The fish doesn't dry out that way. I get the parchment rolls from the Dollar Tree. It doesn't have a coating the way some other parchment paper rolls do to make them oil & moisture resistant. So, I cut a sheet to size and give it a quick rinse under the faucet. It absorbs enough water that the packet doesn't scorch while baking. I also saw someone put a sheet of foil over the parchment packets to stop them from scorching.
On the bottom of the parchment, I put in a couple tablespoons of water. Sprinkle salt and pepper and some dill onto both sides of the salmon. Set on the parchment. Squirt on some lemon juice. (Sometimes I'll add a tablespoon of butter. Tastes great, but that adds on extra fat.) Sprinkle a tablespoon more water on top. Fold over the parchment into an envelope and seal edges. Bake in the oven at 400 degrees, about 12 min. for a fillet, 17 min for a salmon steak. Bake frozen fillets for about 22 min.
Unwrap the packet - watch out for the steam! Check to see if it's done. It should flake easily and be more of an opaque whitish peach color. Re-wrap and put back in for a few more minutes if necessary. Do NOT overcook as the fish will keep cooking for a couple more minutes due to
residual heat even after you pull it out of the oven. If you find it is already a little overcooked, flake apart right away. That will help cool it and distribute some of the heat, so it stops cooking.
It may take a few times to get the timing of how your oven bakes it, to get this right. Don't give up. Salmon is one of my favorite fish to cook. But, I ate quite a few overcooked ones at the beginning.
