You're not paranoid about the lemons Bizi. I bartended and did a lot of waitressing, and it's rare to see anyone washing the lemons, limes, or oranges for garnishes. When I used to order bloody mary's I would specifically say no lime.

My husband is against most vegetables outside of salads, so I get most of mine in during the day- usually raw. I wash everything thoroughly in warm to hot water though. I buy frozen peas and canned corn.
