The Elf Food I Made Makes the Mythical Beast Cry!

The protagonist travels to the Pokémon world and discovers that the people here only care about battles and cultivation, but no one takes the food produced by the Pokémon seriously. Fresh milk from big milk jugs, honeydew from Three Bees, cuticles shed from Slowpoke tails (which can be used as medicine), fermented tree juice from pots and kettles, and even the nacreous layer shed from the shells of giant tongue oysters every year - these are top-notch ingredients and medicinal materials in the eyes of chefs and pharmacists around the world, but in this world they are actually treated as scraps. The protagonist starts from a small restaurant that is on the verge of closing down. He uses the most basic fresh milk from large milk cans to make pudding, and uses the honeydew of Three Bees to make drinks. He transforms the "low-qualified" elves that no one wants into the main force of food supply, and gradually establishes an elven food supply chain spanning Kanto, Johto, and Hoenn. Others tamed elves in order to build a gym, but he tamed them in order to raise them. Producing milk, making honey, making wine, forming beads, and shelling.
