Answer
Haggis, a renowned Scottish delicacy, is a savory pudding made from sheep's pluck (heart, liver, and lungs), oatmeal, onion, and spices, encased in a sheep's stomach. It is traditionally prepared on the occasion of Burns Night, a celebration of the Scottish poet Robert Burns. Haggis is typically served with "neeps and tatties" (mashed turnips and potatoes), and accompanied by a dram of Scotch whisky.
