on the rocks

[Frank_Stein]

Bar glasses should change their name to the booze that's the most prominent in it. If there's another kind, call it a mixed whatever. Don't let other reagents change the name.

Stuff

This idea is basically crippled by this underlying problem.
Mixology should work as a quality prefix construction INVOLVING chemicals, rather than just based off chemicals alone.
For example to make a martini it would require you to construct what goes in, THEN add the chemical, eg:
SUBLIME martini: Olive + Cocktail glass + martini chemical
OK martini: Cocktail glass + martini chemical
AWFUL martini: Any other glass + martini chemical

The prefix is literally just for show and doesn't effect the drink, but it makes being a bartender, and ordering a drink, far far more engaging. It would give the bartender a few simple but worthwhile garnishes (Cherry, lime/lemon/orange wedge, mint, olives, mini umbrella) and other stuff already in-game (cream, salt, ice) that can be used as such. It also opens up the option of heating/cooling things for quality prefix.

The great thing about this is that there's nothing stopping you from adding something in afterwards, the prefix is only applied to the glass construction. So you could make a SUBLIME martini, then add 500 mini umbrellas/unstable mutagen to it and it would still be a SUBLIME martini, you don't see whats in the glass. The bartender would have to be craftier if wanting to poison it if the person is viewing them making the drink.
Bartender could go all out and making horrible drinks, like pissing/vomiting into a glass then adding the chem, making a PUTRID cocktail. PUTRID PISS PORT.

Sky's the limit really, you can add ice to an old fashioned glass then some straight spirit to make "X on the rocks", while stuff like daiquiri could be made frozen style if cooled.

Both of those sound like great ways to do. A glass of rum and a glass of mostly rum and poison would probably both look like a glass of rum.

Maybe when chemicals, drinks, and food are consumed, some text can pop up that describes their unique flavors. A good traitor chef/bartender would stick poisons with drinks of a similar flavor together, or mask it with sugar and spice. For instance, cyanide is supposed to taste like almond. A bartender could stick some in amaretto without anyone picking up on it, but it would be more noticeable in something like a screwdriver.
