Cold Foam, Any Flavour

The base ratio

• 60 ml heavy cream
• 20 ml oat milk
• 10 ml simple syrup
• 1 pinch fine salt

Pick one flavour

• 1 tsp any Superboba tea powder, whisked into 20 ml hot water firstSuperboba
• 1 tsp vanilla extract
• 1 tbsp kinako, cocoa, or black sesame paste
• 1 tbsp liquid honey

1. 1

   Combine the cream, oat milk, syrup and salt in a narrow jug. Narrow matters, because a wide vessel will not build foam.

2. 2

   Add your flavouring. If it is a tea powder, whisk it smooth in hot water first and let it cool, or it will stay lumpy in the fat.

3. 3

   Froth at an angle for 45 to 60 seconds, until it thickens but still pours off a spoon.

4. 4

   Spoon over any iced drink.

• Stop while it still pours. Over-frothed foam sits on the drink like a hat and never marbles down through it.
• The salt is not optional. Without it cold foam just tastes like sweet cream.
• Dairy-free works with a barista oat cream, though it will be slightly looser.
