Gingerette is a spicy ginger simple syrup and the secret to the easiest and most delicious homemade ginger beer. Make a big batch of this (adjust the amount of sugar and ginger to suit your taste) and simply add seltzer water when ready to drink.
1. To make the gingerette, combine water, granulated sugar, and grated ginger in a small saucepan. Bring the mixture to a boil, then reduce and simmer, stirring, until sugar is dissolved. When the sugar is completely dissolved, turn off the heat, cover the saucepan, and infuse for at least 1 hour at room temperature before straining.
2. To make the cocktail, combine the rum, lime juice, and gingerette in the bottom of a highball glass or tumbler with ice. Stir well to combine, then top off with seltzer water.
