Many brands of store-bought eggnog are so thick that their consistency is closer to a milkshake. Fortunately, you can fix this by shaking your eggnog in a martini shaker.

Shaking your eggnog emulsifies ingredients that are at odds with one another and adds air to the drink, giving it a nice, frothy cohesiveness that homemade eggnog has in spades.

Shaking the eggnog with a few cubes of ice can make the drink even better, as the ice dilutes the 'nog a bit, cutting through that over-the-top sweetness of store-bought eggnog.

Simply shake your eggnog vigorously for at least 15 seconds. It’s best to use a cocktail shaker with a built-in strainer to keep

the ice from falling into the drink.
