Tips & Notes

Pro tips

Beat the egg with baking soda until frothy and pale—this creates the signature creamy texture.
Heat milk to steaming (160–180°F) before adding to keep the drink hot and help pasteurize the raw egg.
Pour spirits into the egg mixture slowly while stirring to emulsify, preventing curdling.
Serve immediately in a warm mug or glass to maintain temperature.

Substitutions

Old Mr. Boston Imported Rum → Bacardi or Mount Gay rum (lighter or spiced variants change flavor profile)
Old Mr. Boston California Brandy → Cognac or American brandy (higher quality upgrades the drink)
Hot milk → hot cream or half-and-half (richer, more decadent)

Storage & make-ahead

Best served fresh. Leftover batter keeps refrigerated up to 2 days; do not store the prepared drink.

Equipment

cocktail shaker or mixing glass · whisk or bar spoon

Common Questions

Is the egg in a Tom and Jerry cocktail cooked?

The egg is mixed raw with baking soda and sugar, then combined with hot spirits and milk. The heat pasteurizes it, though some prefer cooked eggs for food safety.
