This could be a slippery slope though. A good tender will use some discretion
based upon experience to give the customer what they want but words and names
still mean things. If you think you know better than the customer what they
want or that your own variation is better than the standard recipe for what
they ordered than there's no point in naming drinks, such that I can go into
any bar and order a cocktail with a reasonable idea of what to expect.
Certainly it's cool if you can talk to your customer and interest them in your
own version of something but I can't condone arbitrarily swapping ingredients
into drinks just because it suits you at that moment.
In spite of the fact that a Whiskey Sour is (whiskey + sour) the name is still
a title, not just a note on what elements to combine. I haven't studied the
origins of this cocktail and I won't claim to know all of it's variations.
Still I would stand by the statement that most sours call for lemon juice
(assuming we're talking about juice and not mixes) unless an exception is
stated. So if it's a Whiskey, Amaretto, Pisco, Midori, etc. it gets made with
lemon juice and an appropriate amount of sugar. Then you've got sours like
the Sidecar and Margarita that add triple sec into the recipe and the juice is
specific to the recipe (e.g. lime in a Margarita).
While I could see someone making a WS with lime juice I've never seen a recipe
for it.
