Coffee strength is everything: use double-strength coffee so the bitterness balances the sweetness.
The secret to creamy texture is the ratio: 2 cups ice to 1 cup liquid (coffee + milk). Blend just until smooth — over-blending thins it out.
Honey acts as an emulsifier — do not skip it.
Chill the glass for 15 minutes beforehand to keep the drink thicker longer.
Adaptations: Dairy-free: use oat milk or full-fat coconut milk. Lower sugar: swap honey for sugar-free vanilla syrup and add extra ice. Mocha: add 1 tbsp unsweetened cocoa powder and extra honey. Cold brew: replace cooled coffee with cold brew concentrate and reduce milk by 2 tbsp.
Freezing: Pour into airtight container and freeze up to 1 month. Re-blend with 1/4 cup milk after thawing.
