In Stardew Valley, you’re not just aiming to make a farming empire. No, no, you must also work on your entire industry. Truffle Oil is a product you’ll be able to produce with a bit of work. It’s going to be asked for within a quest and it can also be donated to the Community Center bundles.
First, you’re going to need a pig. Pigs will bring you truffles that can be sold for 500 coins. They need to be outdoors in order to get you a truffle, though. You can buy pigs from Marnie once you’ve upgraded one of your Barns to the Deluxe size (from Robin, the Carpenter).
Okay, so you have your truffles, now what? Well, you’ll need to build an Oil Maker. It can be crafted once you’ve reached Farming Level 8 with 50 slime, 20 hardwood, and 1 gold bar. Once you’ve placed your Oil Maker, you simply interact with it while holding a truffle and wait five to six hours for your new Truffle Oil.
