in a venti sized cup with no ice (in this ex, it’s mango lemonade), i’d literally do half the shaker with mango, then the other half with lemonade up the end line of the venti indicator. in a cup with light ice, there is a standard in the recipe cards: fill up the venti “base” section, then keep filling into the hollow that says “juice.” after that, fill up the rest with lemonade and go a little bit into the “ice” portion. then, go one scoop down for the ice and you should fill it up just fine. if they asked for “light ice extra lemonade” i’d just fill it up with a normal amount of base and put lemonade up into just under half of the ice line then do a venti scoop. hope this helps!

extra lemonade… y’all are adding water??
