Tom and Jerry Drink with Homemade Batter

A Tom and Jerry is a hot cocktail built on a fluffy egg batter, spiked with rum and cognac, and topped with steaming milk. It tastes like eggnog’s lighter, airier cousin, served warm in a mug with nutmeg grated over the top. The drink belongs to Christmas in the upper Midwest, where supermarkets stock pre-made batter every December, but making your own batter from scratch gives you control over sweetness, texture, and how many drinks you can pour.

What a Tom and Jerry Is and Why It Works

The Tom and Jerry is a hot egg-based cocktail that separates itself from eggnog by whipping the whites and yolks independently, then folding them together into a stable foam. That foam holds its structure when you add hot milk and spirits, so the drink stays light and frothy instead of collapsing into a thin custard.

You serve it hot, which changes the way the alcohol and spice hit. The warmth opens up the rum and cognac, and nutmeg smells stronger when it sits on a steaming surface.

The batter does all the work. Once you’ve made it, assembling a drink takes thirty seconds: a spoonful of batter, a shot each of rum and cognac, hot milk to fill the mug, and a stir. Keep the batter covered in the fridge and stir it gently before using each time.

Ingredients

• Boiling water, to rinse
• 1 ounce dark rum
• 1 ounce cognac
• 1 tablespoon Tom & Jerry batter*
• Whole milk, hot, to top
• Garnish: nutmeg, freshly grated
• Garnish: ground cloves
• Garnish: ground allspice

How to Make the Tom and Jerry Batter

Make this first and let it cool before you build the drink. A good store-bought jar works too.

• 6 eggs, separated and room temperature
• 2 1/4 cups superfine sugar, divided
• Salt, just a small pinch
• 1 teaspoon pure vanilla extract
• 1 cup powdered milk

1. In a small bowl, beat egg yolks until thick; set aside.
2. In a large bowl of your electric mixer, beat egg whites until stiff peaks form. Using a spatula, fold 1/2 cup superfine or granulated sugar slowly into the prepared egg whites.
3. Using your rubber spatula, fold the beaten egg yolks into the egg whites with the sugar.
4. Add the remaining 1 3/4 cups superfine or granulated sugar, salt, and vanilla extract.
5. Still using your rubber spatula, slowly and gradually fold in the powdered milk.
6. Store, covered, in the refrigerator, and use as needed. Will keep up to one week in the refrigerator. Mixture will probably separate in the refrigerator. No problem - just stir and use. The drink will still turn out frothy and delicious.

Instructions

1. Rinse a small coffee mug (white ceramic Tom & Jerry cup) with boiling water to warm it, then pour out the water.
2. Add the rum, cognac and batter to the cup and top with hot milk.
3. Garnish with a mixture of 2 parts freshly grated nutmeg to 1 part each ground clove and ground allspice.

How to Beat the Whites and Fold Without Losing Volume

Stiff peaks mean the egg whites hold their shape when you lift the beaters straight up. If the peaks droop or curl over, keep beating. Underbeaten whites collapse when you fold in the yolks, and the batter turns soupy.

Add the sugar slowly to the whites. Dumping it all at once weighs down the foam before the sugar dissolves. The mixture should look glossy and smooth, not grainy.

Folding is not stirring. Use a wide rubber spatula and work in broad strokes, lifting the heavier yolk mixture up from the bottom and laying it over the whites. Stop as soon as the color is even.

Milk Temperature and Why It Matters

Heat the milk until it steams but does not boil. Boiling milk will cook the eggs in the batter and turn the drink into scrambled egg soup. The milk should be hot enough to keep the drink warm but cool enough to leave the batter intact.

Whole milk gives the drink body. The fat in whole milk also carries the nutmeg and spice flavors better than lean milk does.

A warmed mug keeps the drink hot longer. Pour boiling water into the mug, let it sit for thirty seconds, then dump it out before building the drink.

Spirit Ratios and What They Do

The standard ratio is one ounce each of dark rum and cognac per drink. Dark rum brings molasses sweetness and a bit of funk. Cognac adds fruit and oak.

Some recipes use only rum. That works, but the drink tastes one-note. Two ounces of rum per drink is the right total alcohol if you go that route.

You can make a non-alcoholic version by skipping the rum and cognac and topping with more milk. The drink will be sweeter and less interesting, but it still works as a hot spiced milk with a foamy top.

Common Problems and How to Fix Them

• Flat, soupy batter: The egg whites were underbeaten or the folding was too aggressive. Beat the whites until they hold stiff peaks, and fold gently with a lifting motion instead of stirring.
• Grainy texture in the batter: The sugar was added too fast or not beaten in long enough. Add powdered sugar gradually and beat until the mixture is smooth and glossy.
• Curdled or scrambled eggs in the drink: The milk was too hot. Heat the milk until it steams but does not boil. If it’s steaming heavily or boiling, let it cool for a minute before adding it to the mug.
• Drink separates or looks watery: Not enough batter was used, or the batter was not folded into the liquid thoroughly. Use a full tablespoon of batter per drink and stir gently but completely after adding the milk.
• Batter deflates after a day in the fridge: Egg foam naturally loses volume over time. Keep the batter covered in the fridge and stir it gently before using to redistribute any liquid that has settled.

Storage, Yield, and Batch Math

One batch of batter serves a holiday gathering. If you’re pouring drinks for a small group, one batch is plenty. For a larger party, make two batches and keep the extra in the fridge.

Each drink uses one tablespoon of batter, one ounce each of rum and cognac, and enough hot milk to fill the mug. Add the batter and spirits first, then fill the rest of the mug with hot milk. The milk goes in last so it mixes with the batter and spirits as you pour.

If you’re making drinks for a party, heat a large pot of milk on the stove and keep it warm over low heat. Set out the batter, rum, cognac, mugs, and a ladle. Guests can assemble their own drinks.

Frequently Asked Questions

Is a Tom and Jerry the same as eggnog?

No. Eggnog mixes whole eggs with milk, cream, sugar, and spirits, then chills it. A Tom and Jerry separates the eggs, beats the whites into a foam, folds in the yolks, and serves the drink hot.

Can you buy Tom and Jerry batter in stores?

Yes, in parts of the upper Midwest. Supermarkets in Wisconsin, Minnesota, and the Dakotas stock pre-made batter during the Christmas season. If you live outside that region, you’ll need to make your own.

What is the history of the Tom and Jerry drink?

The drink is attributed to British writer Pierce Egan in the 1820s. Egan wrote a book called Life in London, which featured characters named Tom and Jerry. The cocktail appeared around the same time and took the name.

Do you have to use both rum and cognac?

No, but the drink is better with both. Rum alone works if you use two ounces per drink. Brandy is a fine substitute for cognac.

Can you make the batter ahead?

Yes. Keep the batter covered in the fridge and stir it gently before using. Make it in the morning and assemble drinks in the evening, or make it two days before a party.

What kind of mug should you use?

A standard coffee mug works. Traditional Tom and Jerry cups are short and wide with a handle, and the wide mouth helps the foam sit on top without collapsing.

Conclusion

A Tom and Jerry is a hot egg cocktail that tastes like eggnog but drinks lighter and warmer. The batter is the key: beaten egg whites folded with sweetened yolks create a stable foam that holds up under hot milk and spirits. Make the batter once, keep it in the fridge, and you can pour drinks all week.
