Get a food called "Apple Ice Cream" (available in the inn at Ravennue village) and eat one to learn the recipe, then go back to Bose's market to purchase as much of the ingredients as possible. One of each ingredient equals to about 80 mira while the ice cream itself can be sold for 125 mira. If you mass produce 99 of it and sell it back to the market, you can make about 4000 mira per 99 ice creams sold. Repeat until satisfied and when funds start to drain.
