If you´re drink tastes much better than "usual" Amaretto Sour although having
a skunk smell, you might think about some details:
Do you like Amaretto?
Do you like Sours?
How old was the lemon juice?
Did you clean the glasses and the shaker before using them?
If there are four "Yes", you might give a real Amaretto Sour a second chance,
using Amaretto (di Saronno), lemon and orange juice (instead of sour mix).
