Ireland was the first European country to accept the potato as a serious food crop and potatoes have been the mainstay of the Irish diet since the 16th century. Champ is one of the many traditional Irish dishes that potato appears as its main ingredients. The recipe is believed to originate from the kitchens of farmhouses in the Ulster countryside. It consists of spring onions and mashed potatoes, which are inexpensive and can be locally grown even in bad conditions such as poor soil or cold weather.
Champ is commonly served on St Patrick’s day.
