Haggis, Neeps & Tatties is a traditional Scottish dish consisting of haggis, mashed turnips (neeps), and mashed potatoes (tatties). Haggis is a savory pudding made from sheep's heart, liver, and lungs, mixed with oats, onions, and spices. The neeps are cooked until tender and mashed with butter, while the tatties are boiled and mashed until smooth. This hearty and flavorful dish is often served on Burns Night, a celebration of the Scottish poet Robert Burns.
