((hamster-bamster)) - you sound like a glorious cook and a perfectionist. You're right your guests won't know if the produce is organic or not. The only thing I do with guests is, make sure they don't have allergies and whether they're vegetarian....that's it lol. I don't ask them what they want or what dessert they want. If I were you, don't apologize for anything - I would be so happy to eat what you're making. Take a deep breath, cook your little heart out and everything will be fine. Best of luck and bon appetite
