How do they make the asparagus white? I'm glad you asked. Asparagus turns green once it's spears break the surface of the ground and get chlorophyll from the sun. Farmers here cover their fields in rows of sun ray-blocking sheets of opaque white plastic, and the tender spears get pulled from the ground before seeing a single second of sunshine.
Why do they make asparagus white? Good question. Chefs swear white asparagus is completely different from green. Maybe my tastebuds are majorly unrefined, but I have yet to taste a difference.
