What is the main ingredient in a traditional Scottish haggis?

The main ingredient in traditional Scottish haggis is sheep's heart, liver, and lungs, which are encased in the animal's stomach. This unique combination of organ meats is what gives haggis its distinctive flavor and texture, embodying the traditional Scottish cuisine that emphasizes using all parts of the animal. The mixture is seasoned with spices and oats, which are often included to add bulk and texture.

Haggis is not based on beef or pork, as these meats are not part of its traditional preparation. Chicken is also unrelated to the defining characteristics of haggis. The use of heart, liver, and lungs reflects the resourcefulness and cultural heritage of Scottish cooking, where no part of the animal is wasted, and creates a dish that is rich in flavor and history.
