I keep seeing all these different figures for making the lemonade in bulk and I have no idea where folks are getting their figures from or if maybe they're just very bad at math ;+D. Below is the "correct" amounts for making bulk quantities of the lemonade.
To make 30 oz or approx 1 quart (32 oz) 3 drinks
24 oz water
3oz lemon Juice
3oz maple syrup
3/10ths tsp cayenne (approx 1/4 rounded tsp)
For 60 oz approx half gallon(64oz) - 6 drinks - Multiply quart recipe x2
For 120 oz approx 1 gallon (128 oz) = 12 drinks - Multiply quart recipe x4
For Ya'll across the big pond here the rounded off Metric per drink conversion:
