If I'm being honest, the best way to memorize is to just get practice on bar. I was at a drive thru so business was nonstop, but I got really good practice. Now I'm at a cafe and am super confident. All it really took was practice. Don't be afraid to always ask questions either! bother your coworkers if you have to haha

When I first started I looked up a lil picture sheet that showed the pumps and shots in each size with exceptions and made it my lockscreen :-) you can also scroll through the app when you feel like it and look at what goes in each drink and each size. Practice makes you memorize it best

it honestly takes practice. Keep some notes on a flash card and keep it next to you while you bar. You will get it sooner or later. They used to put me on bar every morning for a few hours and i would just look and my flash cards and one day i just didn’t need it anymore
