Instructions

Cocktail

Add the lemon juice, rum and simple syrup to a cocktail shaker.
Fill the shaker with ice and shake well about 15-20 times.
Strain out the ice, and add the egg whites. (Use a tumbler to collect the liquid if you don't have a 2-sided cocktail shaker.)
Seal the shaker without ice, and do a dry shake for at least a minute. If you prefer, you can use a milk foamer to froth up the mixture.
Pour the mixture through a fine mesh strainer into your cocktail glass.

Garnish

Use your bitters bottle to add a few drops of bitters to the top of the foam.
Using a cocktail pick or toothpick, drag through the drop of bitters to make a heart style design.
Clip the dehydrated lemon to the rim of the glass, and serve.

Notes

Egg Whites - I used pasteurized egg whites, but you can also use fresh egg whites if you prefer. Or, you can use aquafaba (liquid from cooking chick peas) or a store bought cocktail foamer for a vegan option.
Syrup - You can substitute in maple syrup if you don't have simple syrup. Or, try using Orgeat for some delicious almond flavor.
If you prefer to omit the egg whites, just make it with the same ingredients. You can either serve it up with no ice, or serve in a lowball glass with ice. Try topping with seltzer if it's too strong for you.
