Haggis

Haggis is a Scottish dish that is prepared by using a sheep stomach, oatmeal, suet, and other ingredients.

Mainstream Smurfs Media
Although the food itself doesn't actually appear in mainstream Smurfs media, Gutsy Smurf in the 2011 Smurfs movie told the hog-tied Patrick Winslow that he would have made haggis out of Patrick's innards if his wife Grace didn't step in and showed that Clumsy was safe.

Empath: The Luckiest Smurf stories
Haggis is mentioned a few times by Duncan McSmurf in the EMPATH: The Luckiest Smurf story series, but it is uncertain if the Smurfs even tried to make or eat it.
