With a base selling price of 625g, farming Stardew Valley Truffles is one of the fastest ways to make money. Depending on the star rarity of the mushroom, the price will go over a thousand. Although it is a gourmet type, it is used to produce craft goods, which are sold for even better prices. Like the other types of mushrooms, you do not have to gather it from outside the farm. It is found or produced by an animal, whose use you may still be looking for.

You would have to invest a bit to get Truffle, but it would be worth it if you earn more than that. So before we start the topic, earn some Gold if you are low on it.

Truffles are left outside the barn by the farm's adult and fed pigs. They will leave it on the tiles without any flooring or items, so make sure you have free space when you bring them outside. Pigs live in the Deluxe Barn which is upgraded from the Big Barn with 25,000g, 550 wood, and 300 stone. Once you have built this barn, go to Marnie's Ranch and buy a pig for 16,000g. You can also buy these mushrooms from the Traveling Cart for 1,875 – 3,125g, but they rarely appear in stock.

There is a 99.9% chance that the pig will drop the first Truffle of the day if it walks on many free tiles. After the first one, the speed depends on the Friendship. The formula to find the speed is Animal Friendship/1500. This means that if you have 1000 (Max) Friendship points, there is a 66% chance that it will drop a Truffle. On average, the number of mushrooms the maximum lucky pig will drop is three.
