Fresh lemon is a yellow citrus fruit whose juice and oil-rich peel are a core souring and aromatic element in the bar.
Roll it firmly on the board before cutting; that frees juice the squeezer would otherwise leave behind. One fruit yields 30 to 45 ml, depending on size. The juice sours, the peel gives oil for a twist, and a wedge in the glass lets the drinker add more.
Lemon peel and juice
A strip of peel and a barspoon of juice replace wheels shaken with the drink.
Meyer lemon
This hybrid is more aromatic and gentler. Its wheels and peel swap straight in.
Its wheels work just as well.
Wheels add a pleasant scent but lack sourness.
Bottled lemon juice
It brings the sourness but misses the fresh citrus aroma. If you can, add a strip of fresh peel.
Lemons keep for weeks. Commercial storage runs warmer than a home fridge, and drying from the ends is chill damage as much as age. Unwaxed fruit is worth finding if you use the peel.
