Sarsaparilla

Sarsaparilla is a plant that is one of the most favorite foods of the Smurfs, besides smurfberries. It can be either eaten raw or made into other types of delicacies or ingested in liquid form.

Empath: The Luckiest Smurf stories
Sarsaparilla appears in the EMPATH: The Luckiest Smurf story series as a common form of food that's second only to smurfberries. Mostly it is served in liquid form as sarsaparilla ale that's brewed by Tapper Smurf, or as sarsaparilla soup that's made by Greedy Smurf. Nabby tends to be the only Smurf who constantly eats raw sarsaparilla leaves. While Empath himself finds sarsaparilla leaves edible, he prefers it mostly in liquid form.
