The Deep Fryer is a small kitchen appliance found in the Player's Home. It is used to make French Fries and Homemade Poutine, but cannot be used until the fryer basket is installed. To get the basket, the player must reach Friendship Level 50 with their Mother.
To make French Fries, the player must bring two full Harvesting Baskets of Potatoes near the French fry cutter. Pressing on the cutter's handle will add a 5% of fries to the frying basket, and consumes 10% of Potatoes from nearby Harvesting basket in the process. When the fryer is full, interacting with the blue tape near the sink will package the fries into a bag, and spawn that bag on the stove.
To make Homemade Poutine, the process is similar to above. First is cutting the potatoes into fries as normal. Then, after cutting, the player needs to add a pack of Cheese Curds to the fries, and press the power button on the cooker. After a short time of cooking, bowls of poutine will begin spawning beside the fryer, one bowl per 20% of the fryer filled with fries.
