It is cold. Not just "I need a light jacket" cold, but that bone-deep, damp winter chill that makes you want to hibernate until April. This is when most people reach for Swiss Miss or maybe a glug of eggnog from a plastic carton. But if you grew up in the Upper Midwest—think Wisconsin or Minnesota—you know there is a better way. You know about the Tom and Jerry recipe. It isn't just a drink. Honestly, it’s a ritual.
Most folks get it confused with eggnog. I get it. They look similar in the mug. They both involve eggs. But if you call a Tom and Jerry "warm eggnog" in a dive bar in Green Bay, you might get kicked out. One is a heavy, milk-based liquid you buy at the grocery store; the other is a stiff, spicy, meringue-like batter that sits on your counter in a ceramic bowl, waiting to be brought to life with boiling water and a heavy pour of brandy.
The Weird History of a Drink Named After a Book (Not a Cat)
You probably think this has something to do with the cartoon. It doesn't. Tom the cat and Jerry the mouse didn't show up until 1940. This drink is much older. Most historians, including the legendary David Wondrich in his book Imbibe!, trace the Tom and Jerry recipe back to a British journalist named Pierce Egan in the 1820s.
Egan wrote a book called Life in London, featuring characters named Corinthian Tom and Jerry Hawthorn. To promote the book (basically 19th-century influencer marketing), he created a variation of egg flip. He added a half-ounce of brandy to the traditional rum-based drink. It was a massive hit. Suddenly, "Tom and Jerry" became slang for young men causing trouble in London. Eventually, the rowdiness faded, but the batter remained. It migrated across the Atlantic and found a permanent home in the coldest parts of America.
Why the Midwest Kept It Alive
If you walk into a liquor store in Milwaukee in December, you’ll see tubs of "Tom and Jerry Batter" in the dairy case. Brands like Mrs. Bowen’s or Connolly’s have been staples for decades. Why? Because it’s a pain to make from scratch. But the homemade version is so much better. The commercial stuff is often just flavored sugar. Real batter involves whipping egg whites until they form stiff peaks, which gives the drink its signature "cloud" on top.
The Anatomy of a Proper Tom and Jerry Recipe
Let's talk logistics. You can’t just throw things in a blender and hope for the best. This requires a bit of technique.

The Batter is the Soul
First, you separate your eggs. This is non-negotiable. You beat the yolks with a mountain of sugar, vanilla, and spices—usually cinnamon, cloves, and allspice. Then, you whip the whites separately. This is the secret. You fold those whites back into the yolk mixture until you have something that looks like marshmallow fluff but smells like a spice cabinet.
The Booze Choice Matters
Traditionally, it’s a mix. You want a dark, funky Jamaican rum and a decent brandy or Cognac. Some people use bourbon, but that’s a bit of a departure from the classic profile. The brandy provides the fruitiness, while the rum gives it that deep, molasses backbone.
The Temperature Fixation
You don't use warm milk. You use boiling water. Or, if you’re feeling extra, a mix of boiling water and hot milk. The heat from the liquid cooks the egg batter just enough to thicken it in the mug, creating a creamy, frothy head that stays until the last sip.
How to Make the Batter (The From-Scratch Method)
You'll need a dozen eggs. Yes, twelve. This isn't a "single serving" situation. You make a bowl of batter and you invite the neighbors over. That's the whole point.
- Separate the eggs. Put the whites in one big bowl and the yolks in another. Make sure no yolk gets into the whites, or they won't fluff up. It's science.
- Yolk prep. Beat those yolks until they are thin. Slowly add about a pound of powdered sugar. Throw in a teaspoon of salt, a teaspoon of ground cinnamon, half a teaspoon of ground cloves, and half a teaspoon of ground allspice. A splash of vanilla extract goes in now too.
- The Fluff. Use a hand mixer on those whites. Beat them until they are stiff. You should be able to turn the bowl upside down over your head without getting hit with egg.
- The Fold. Gently, and I mean gently, fold the whites into the yolk mixture. Don't stir. If you stir, you pop all the air bubbles and the drink will be flat and sad.
Serving It Like a Pro
Take a pre-heated mug. Plop a massive tablespoon of the batter into the bottom. Add one ounce of brandy and one ounce of dark rum. Fill the rest of the mug with boiling water or hot milk, stirring constantly as you pour. The batter will rise to the top like a glorious, spicy foam. Grate fresh nutmeg over it. Don't use the pre-ground dust. Buy a whole nutmeg and a microplane. It makes a difference.

Common Mistakes That Ruin the Experience
I’ve seen people try to make a Tom and Jerry recipe and fail because they ignored the temperature. If your water isn't boiling, the batter won't "set" in the mug. You’ll end up with a lukewarm, separated mess.
Another big one: using granulated sugar instead of powdered sugar. Granulated sugar can leave the batter gritty. Powdered sugar (confectioners' sugar) has a tiny bit of cornstarch in it, which actually helps stabilize the foam. It stays fluffy longer on the counter.
Also, don't skimp on the spices. The eggs and sugar are heavy. They need the "bite" of the cloves and allspice to cut through the richness. Without it, you're just drinking hot sugar-egg-water. Nobody wants that.
Is It Safe? The Raw Egg Debate
Since the batter uses raw eggs and is then hit with hot (but not necessarily boiling-for-long) water, people worry about salmonella. It’s a valid concern. If you’re worried, use pasteurized eggs that come in the carton, or pasteurize your own eggs at home using a sous vide setup ($135^{\circ}F$ for 75 minutes). Most people in the Midwest just live on the edge, but for the elderly or immunocompromised, pasteurized is the way to go.
The alcohol also acts as a bit of a preservative, but don't leave the batter out on the counter for twelve hours. Keep it in the fridge and just bring it out when you’re ready to serve.

Why This Drink Survives in the Modern World
We live in an era of "instant everything." You can get a pumpkin spice latte in thirty seconds. But the Tom and Jerry recipe persists because it forces you to slow down. You can't rush the egg whites. You can't rush the boiling water. It’s a communal experience. You see the big ceramic bowl on the sideboard and you know the party has started.
It’s also surprisingly versatile. I’ve seen people swap the water for hot apple cider, which is honestly a game-changer. Some folks skip the rum and just go with a high-proof bourbon. It’s a template for winter comfort.
Taking Action: Your Weekend Project
If you want to master this, don't wait for Christmas Eve. Do a trial run.
- Step 1: Buy a set of Tom and Jerry mugs. You can find the vintage milk-glass ones on eBay or at thrift stores for cheap. They usually have "Tom and Jerry" written in Old English font. It makes the drink taste better. Fact.
- Step 2: Get the good booze. Don't use the $8 brandy. Get something you’d actually sip on its own.
- Step 3: Make the batter on a Saturday afternoon. If you have leftovers, it stays good in the fridge for about 3 days. Just re-whisk it gently if it settles.
- Step 4: Invite three friends over. This drink is too heavy to consume alone. It requires conversation and a fireplace (or at least a YouTube video of a fireplace).
The beauty of the Tom and Jerry recipe is its resilience. It survived the Victorian era, Prohibition, and the rise of modern mixology. It’s still here because it works. It’s warm, it’s boozy, and it feels like a hug in a mug.
Stop settling for mediocre holiday drinks. Go buy a dozen eggs. Start whisking. The effort is worth the reward.
