A bit late, so everyone may already know of these things, but I wanted to share some more end game strats.
To get all your food recipes and crafting, you'll want to first Rank/Grade up a yellow shard called Alchemical Bounty. It's dropped by the ox enemy near where you can play the piano.
Once maxed, it has a chance to craft 3 items for you instead of one. This goes for food as well.
Especially useful for the food quest, since she takes the food you make. But if you get 3 copies, you can give one to her, eat one yourself for the stat boost, then either keep the last or dismantle it to get the ingredients back.
You can reset the game until it crafts you 3 copies of something.
But to max out that Shard, you need a rare ingredient called Gold. And the best way to get Gold is probably to dismantle Ayamur. Which is dropped by the horse enemies under water. One is right next to a teleporter.

Once you have dismantled one into Gold, dismantle the Gold as well, and then craft one. If you're lucky, you'll get 3 copies instead of one. If not, you can rest the game until it works. And then you can rinse and repeat, by dismantling the gold, and crafting 3 new ones. Or farm more Ayamur.
But to dismantle items/food you need Alkahest. And this is the best place to farm Alkahest, as far as I know.
Since those enemies drop x2 Alkahest per drop.
Also, if you want to farm money, this may be the best place to do it:
