That's right, you can eat Hosta shoots. You want to look for tightly curled shoots that emerge first in Spring or after mowing the hostas down, shoots will emerge after. Cut off the shoots about a finger's length and rinse well.
Fresh shoots have a taste similar to butter lettuce and a slightly mucilaginous texture to them. They are crunchy and fresh tasting.
Once you cook them, the shoots take on the flavor and texture of mild asparagus. Just fry them quickly in a hot skillet until they start to turn a caramelized brown.
