honestly repetition the more time you spend on bar the better you get at it. and the quizlets definitely help. don’t stress too much ask questions when you need to and know you’ll eventually get the hang of it.

also at my store we have little charts on bar for training that tell us the number maybe yours has some too? but mostly its just repetition

I personally can remember numbers better so this is the method I came up with:

(1st digit is the shots, 2nd digit is the pumps)

Hot drinks: 12, 13, 24, 26

Iced drinks: 14, 25, 36

Practice, practice, practice. And don't be afraid to ask questions. For example, if you get some bar time, of course it'll be with someone who's available to coach you as needed. Even if it's every drink for the first few, ask them for a reminder on how many pumps/shots and stuff, and eventually you'll remember and not have to ask until a new one comes up... And then you do the same thing again, you'll just get it all down with practice and repetition.

You can also pay attention to the POS as you are taking orders in a different position, look at the side bar and see what's in each one for a refresher on the numbers when you aren't on bar.

Worse case I ring it up on reg and it shows you the recipe and how much of whatever goes in it
