It's simple, this mod adds Tacos to Minecraft.
Tacos require 5 ingredients: Chopped Tomato, Grated Cheese, Chopped Lettuce, Ground Beef, and a Flour Tortilla.
Tomato plants can be found in forests and birch forests. Harvesting the plant will yield tomato seeds that can be planted on farmland. The tomato plant works similarly to berry bushes. Every so often tomatoes will grow on planted tomato plants. Shears can be used to harvest them. These can be chopped in a crafting table with a knife.
Cheese can be acquired from the curdling of milk in a vat. You can fill a vat with milk similarly to a cauldron. After a certain time, the milk will convert to cheese. You can use a knife to remove the cheese. You can grate it with a grater in a crafting table.
Lettuce plants generate naturally in jungle and plains biomes. When harvested with shears one plant will yield several leaves of lettuce. These can be chopped in a crafting table with a knife.
Cooked beef/steak can be ground by a meat grinder into ground beef.
Tortillas are made with flour, water, and vegetable oil. Wheat can be ground into flour with a Mortar & Pestle in a crafting table. Carrots can be brewed into vegetable oil.
(Note: I know the crafting recipe calls for an "uncraftble potion," it's supposed to be a water bottle and will work with water bottles. It is a glitch in the Minecraft code)
