Chef John’s “State Fair” Lemonade
This lemonade recipe is for real, authentic, vintage lemonade —the kind you might enjoy on a hot summer day at one of those stands at the state fair. Most of us make lemonade just out of lemon juice, but as you may know, the oils in the lemon peel contain a tremendous amount of flavor, and once you drink this, you won’t want to go back to drinking it how you used to.

Instead of just warning about wax on the lemons, they should also inform that oftentimes lemons are sprayed with pesticides after picking, rendering the peel unfit for human consumption. Look out for untreated lemons if you want to use the peel.
