- Can I use brewed coffee?
- Instant coffee is recommended for the specific foam structure and concentrated flavor. Brewed coffee adds too much liquid, making the drink watery.
- Dairy-free options?
- Oat milk or almond milk work great, though the foam might be slightly less stable than with cow's milk.
- Why is it separating?
- This is natural without commercial stabilizers (xanthan gum). Just give it a stir with your straw!
Iced Chocolate Frappe
A Frappe relies on the surfactant properties of spray-dried instant coffee, which forms a stable, thick foam when agitated with a small amount of water. This recipe blends that aerated coffee base with chocolate syrup and milk, creating a suspension that is thicker and creamier than a standard iced latte without needing ice cream.

Equipment Needed
- High-Speed Blender: Standard blenders often leave chunks of ice. A high-power blender creates that signature smooth, slushy "frappe" consistency.
- Tall Glass: For serving. Chill the glass in the freezer for 10 minutes beforehand to keep your drink frozen longer.
- Shaker or Jar: To pre-dissolve the instant coffee. Pouring hot water directly into the blender with ice melts the ice prematurely.

Instructions
1
✓
Create the foam base: dissolve coffee in hot water and shake/froth.
Tip: Freshly brewed espresso won't work the same way due to the oils; instant coffee is chemically required for that specific stiff foam structure.
2
✓
Blend liquids and ice.
Tip: Start with less milk than you think. You can always dilute it, but if it's too watery, the ice crystals will separate rapidly.
3
✓
Blend until smooth.
Tip: Listen to the blender. When the crunching stops and a vortex forms, the ice is fully pulverized into a slush consistency.
4
✓
Serve immediately.
Tip: Gravity will separate the foam from the liquid within 10 minutes. Drink fast or stir often.
