Make cold foam.Put half & half and simple syrup into a French press and pump plunger up and down 40 times. The milk will nearly double in volume.
Combine coffee, caramel sauce, and salt in a cocktail shaker. Shake well.A cocktail shaker is the easiest to use but any airtight container can be used to shake the ingredients together. A jar with a tight lid or a wide-mouth water bottle will both work.
Assemble drink.Pour salted caramel coffee into a cup with ice and top with cold foam.
Simple syrup can be easily made by stirring together one part sugar and one part hot water.
Coffee Options
Cold brew coffee: The easiest and best way to make this drink at home. Use my method to make it perfect.
Strong coffee from coffee machine: Make slightly strong coffee than you usually make by adding 1/2 -1 tablespoon more ground coffee to make a cup. Cool it down in the refrigerator (at least one hour) or in the freezer (15 minutes).
Nespresso or Keurig: Use a pod or capsule to make a cup of coffee then cool it down in the refrigerator or freezer.
Espresso: Pull 2 shots of espresso and add 3/4 cup cold water to make a cup.
