Haggis is a traditional Scottish dish made from sheep's offal, which includes the heart, liver, and lungs, mixed with oatmeal, suet, and spices. This mixture is traditionally encased in the sheep's stomach and then boiled. Haggis is often served with neeps (mashed turnips) and tatties (mashed potatoes), making it a hearty meal. The dish is famously associated with the Scottish poet Robert Burns, who wrote a poem titled "Address to a Haggis." Haggis is celebrated during the annual Burns Night on January 25th, where people gather to honor Burns and enjoy this iconic dish.
