Bull's Milk

Pro tips

• Dissolve powdered sugar completely in the spirits before adding milk to ensure even sweetness throughout.
• Use whole milk for richness; skim or low-fat milk will thin the texture and mouthfeel.
• Serve immediately over ice to prevent separation between dairy and alcohol.
• Stir gently rather than shake to minimize foam and keep the drink silky.

Substitutions

• Old Mr. Boston Rum → other aged rum or spiced rum (adjusts sweetness profile)
• Old Mr. Boston Five Star Brandy → cognac or VS brandy (similar warmth, slightly smoother)
• Powdered Sugar → simple syrup or honey (use ½–¾ oz to avoid over-sweetening)
• Milk → heavy cream or evaporated milk (richer, more decadent result)

Storage & make-ahead

Mix components separately and combine just before serving; prepared cocktails should be consumed immediately. Spirits and sugar keep indefinitely; use fresh milk only.

Equipment

cocktail shaker or mixing glass · jigger for measuring

Can I make Bull's Milk with different spirits?

Yes. Substitute the rum with bourbon or whiskey, or swap brandy for cognac. Keep the ratio of spirits to milk consistent for balance.

Should Bull's Milk be served hot or cold?

Traditionally served cold over ice, though it can be warmed gently for a hot cocktail version. Avoid boiling to prevent curdling.

Why did my Bull's Milk curdle?

Curdling occurs when alcohol proof is too high or milk temperature is too warm. Use room-temperature milk and pour spirits carefully, or add a splash of cream to stabilize.

Can I make Bull's Milk ahead of time?

Mix the spirits and powdered sugar in advance, but add milk and ice just before serving to prevent separation and maintain freshness.
