Fortunately, lightly sprouted potatoes can still be saved. If the potato is firm, with small sprouts and no green coloring, you can cut away the sprouts and peel off any green areas. Soft spots should also be removed, as they indicate spoilage. However, potatoes that are mushy, strongly green, foul-smelling, or heavily sprouted are best thrown away. When uncertainty creeps in, caution is always the wiser choice.
