There’s a few for me. Yamok sauce. Various synthohols. The desserts Troi’s always eating (or being). But most especially gagh. I wouldn’t let the fact it’s some kind of living worm distract me from the way all the cool people describe it. If Riker likes it, I think I would too and I certainly wouldn’t want to look like a p’taQ in front of Riker.
I think people will experiment like crazy. Think about Miles and his scotch flavored gum. Now imagine that with any flavor. Someone like Deanna could make literally all of her food taste like chocolate if she prefers. The replicator could just add the right macro nutrients and vitamins and she’d be good to go.
