Creme de Menthe Frappe

Pro tips

• Chill your glass in the freezer for at least 10 minutes before serving to slow dilution.
• Use crushed ice rather than cubes for faster, more even chilling without over-blending.
• Shake vigorously for 10–15 seconds to create the ideal creamy, frothy texture.
• Taste before serving; adjust sweetness or mint intensity by varying the ratio of liqueur to cream or milk.

Substitutions

• Old Mr. Boston Creme de Menthe → any white or green Creme de Menthe (flavor intensity may vary)
• Heavy cream → whole milk or half-and-half (lighter, less rich result)
• Sugar syrup → simple syrup or honey syrup (adjust ratios to taste)

Storage & make-ahead

Frappés are best enjoyed immediately. Pre-batch the liquid ingredients (no ice) in the refrigerator for up to 2 days; shake with ice when ready to serve.

What is the difference between a frappe and a frozen drink?

A frappe is shaken or blended with ice to create a smooth, chilled texture, while frozen drinks are typically blended into a slushy consistency.

Can you make a Creme de Menthe Frappe without alcohol?

Yes; substitute the Creme de Menthe with mint syrup, mint extract, or fresh mint-infused simple syrup for a non-alcoholic version.

Should you use white or green Creme de Menthe?

White Creme de Menthe is colorless and milder; green has a stronger mint flavor. Either works, depending on preference.

How do you keep a frappe from becoming too diluted?

Use crushed ice rather than cubed ice, chill your glass beforehand, and serve immediately after shaking or blending.
