How to Make It
Preheat the oven to 350°. Spread the almonds in a pie plate and toast for about 8 minutes, or until golden. In a small saucepan, combine the sugar and water and bring to a boil, stirring until the sugar dissolves. Add the milk, corn syrup and almonds and refrigerate overnight.
Puree the almond mixture in a blender until smooth. Strain through a fine sieve, pressing hard on the almonds; discard the almonds. Transfer the liquid to a roasting pan and freeze, stirring occasionally, until semi-solid, about 3 hours.
Transfer half of the ice milk to a blender. Add half of the tea and blend until smooth and frothy. Pour into small glasses. Repeat with the remaining ice milk and tea.
