There are many ways to make a julep, simple enough as it may seem. Indeed the drink is concise, and perfect in its honesty. Here’s one way to keep it true.
Pluck 6-8 large mint leaves, adding to your tin with a spoonful of sugar. Add a measure of bourbon (in this particular instance, 2 ounces), and muddle for 2-3 seconds. Exercise caution so as not to over-muddle. You want the oil from the mint, not its blood. Fill your Lewis Bag with a heavy scoop of ice, and apply your mallet. Fill your tin with the now crushed ice, and garnish with fresh mint sprigs, spanking them first to activate the bouquet. Add a straw if you must.
