The name, effects, and image of the food or elixir you produce is not important. The sell value of your cooking is entirely dependent on only two factors:
- The value of the ingredients you use
- How many ingredients you use
The price is determined by the following formula:
- Add the value of the ingredients together.
Multiply this by:
- 1.5 if you used one ingredient
- 1.75 if you used two
- 2.05 for three
- 2.4 for four
- 2.8 for five
Round the resulting number to the next ten. (101 -> 110, 87 -> 90, etc)
Here's an example:
You cook four Gourmet Meats. Each meat sells for 35 rupees. Add them together and you get 140. Multiply this by 2.4 because you use four ingredients. This gives you 336, so you need to round it up to the next ten, which is 340, the sale price.
So the most profitable meals and elixirs you can cook are simply the ones made with five of the most expensive ingredients you can find.
Just make sure they actually produce something edible, because if you end up with "Dubious Food" or "Rock-Hard Food", they will sell for next to nothing.

You can only obtain a single piece per encounter with a dragon so there's no point in shooting at them more than you have to. You only need to shoot at them until a flash of light where you hit them appears. That flash is the shard that will eventually fall down. Additional shots will yield nothing. In my experience, it's better to use a single arrow bow as close as possible to ensure that you hit the part you want. I couldn't tell if using stronger or weaker bows make a difference (I'm at the point in the game where all I have are bows 30+).
As for favorable spawning points, it can vary from time to time but here's some places I used to farm them and the time of days. They may or may not spawn immediately, try camping again at the time specified until they do. It will help to have a full set of Climbing clothes as you'll want to be climbing around to get to the best spots. Also having a fire sword/spear to light your fires for camping.
Dinraal
Due south of Hebra Tower there's a ledge where a Korok is hiding on the northern face of the canyon wall. Set up camp there on the eastern end of the ledge and wait until Morning to find him. Dinraal will be flying in from the northeast and will fly right though the canyon. When he's close enough and you feel the breeze, jump toward the center of the canyon and wait til you are close enough. Then take your shot.
I recommend using a full set of Flamebreaker armor for the Fireproof set bonus so the fire he breathes doesn't hurt you.
Naydra
West of Mount Lanayru is the Lanayru Road - East Gate. Further in toward the Lanayru Promenade is a ledge on the south wall overlooking a platform on the north wall path. Set up camp at the top and wait until Morning. Naydra will be flying in high in the sky to the east from Mount Lanayru. He will fly right through the canyon very low and up close. Depending on the parts you want, you'll want to shoot from above for the scale, fang or horn. If you want claws, it would be easier to shoot from the north wall ledge.
I recommend using a full set of Snowquill clothes for the Unfreezable set bonus so the ice balls he breathes don't hurt you.
Farosh
At Lake Hylia on the south tower of the Bridge of Hylia is a great place to camp. Wait until Night. Farosh will emerge out of the lake from the north east corner. He should come out immediately after getting getting up at 9pm (2100). If not, wait again until he does. Otherwise, you could try waiting til 1am (0100) in the late late night. But he always came immediately when I tried. He will first fly toward the west and will loop back and fly toward the east in front of you. Wait until he's close enough to feel the breeze then jump out along the bridge. Take your shot when you're close enough.
I recommend using a full set of Rubber clothes for the Unshockable set bonus so the lightning he shoots doesn't hurt you.

They're always in the same spot (and after a Blood Moon, they all respawn). You can see a full map of them at IGN's Hyrule map.
You can find a few types of bosses:
A worthwhile mention is Lynels. They don't get a health bar, but they're stronger than most bosses and drop some crafting materials for end-game stuff as well. They're also the only enemy that grows stronger as you defeat Titans, rather than through the standard difficulty scaling system (or not at all for bosses).
