0.3 teaspoon nutmeg freshly grated plus more for topping
0.8 cup best-quality rum dark
14 ounce condensed milk sweetened canned
Equipment
bowl
whisk
sieve
plastic wrap
Directions
Whisk the eggs and lime zest in a large bowl until well combined and smooth, about 30 seconds.
Add the condensed milk and half of the rum and whisk until combined.
Whisk in the remaining rum, the nutmeg and bitters until smooth. Strain through a fine-mesh sieve and transfer to a jug. Cover with plastic wrap and refrigerate overnight or up to 3 days-it gets better with time.
Stir the mixture well before serving.
Pour into ice-filled glasses and sprinkle with grated nutmeg.
