My Pokemon Cuisine Has Legendary Beasts Drooling!

The protagonist transmigrates to the Pokemon world and discovers that everyone here cares only about battling and training, while nobody gives any thought to the ingredients Pokemon produce.

Miltank milk, Combee honey, the layer of skin that sloughs off Slowpoke Tails and can be used medicinally, Berry Juice fermented by Shuckle, even the mother-of-pearl Shellder shed when they molt each year: to chefs and apothecaries around the world, these are top-grade ingredients and medicinal materials, yet in this world they're treated as scraps.

Starting with a small restaurant on the verge of bankruptcy, the protagonist uses basic Miltank milk to make pudding and Combee honey to mix drinks. He turns unwanted Pokemon with “low potential” into the backbone of his ingredient supply, gradually building a Pokemon ingredient supply chain spanning Kanto, Johto, and Hoenn.

Other people catch Pokemon to challenge Gyms. He catches them to raise them: for milk, honey, wine, pearls, and shed shells.
