The rule
When to blend
Blend for frozen drinks — Piña Coladas, frozen Margaritas, and similar. Texture is the point.

The big idea
Blending is a texture method — crushed ice and short cycles. Serve immediately before it separates.
Keep these
Use for frozen Margaritas, Piña Coladas, and similar texture-first drinks.
Prefer crushed or small ice so the blender doesn’t stall.
Pulse first, then blend smooth — don’t obliterate herbs into bitterness.
Cold dulls sweetness — frozen drinks often need a touch more syrup than the same drink shaken. Taste at serving temp before adjusting.

Large cube
Slow melt · stir, rocks

Cracked
Fast chill · hard shake

Crushed
Texture · swizzle, julep
Use crushed or small cubes so the blender doesn’t struggle. Pulse to start, then blend until smooth. Serve immediately before it separates.
In the glass
Read the drill, then make the drink once focusing on that cue — repetition beats another paragraph.
