Weigh, dilute and fresh citrus
Weigh your cocktail to calculate how much to dilute with water and only squeeze citrus the same day.
In Why We Stir and Why We Shake, we learned that these techinques dilute the drink with right amount of water. When making a batch of cocktails, we need to be more intentional in our dilution.
Note that if you are serving the drink in a punch bowl with ice, you will want to account that into your dilution plan as well.
I've find people are more tolarant of a over diluted drink OVER a under diluted drink. So err on that side.
I'd like to do a few experiments using the method above to see if there is a rul of thumb to % water in shaken and stirred drinks. Assuming shaken will have high dilution than stirred.
