Recently I bought a commercial blender to make fruit smoothies. Being a coffee junkie I wanted a coffee smoothie recipe. Most recipes I found started with instant coffee – not going to happen. I tried making strong hot coffee, adding milk, sugar and ice and blending. The result was a bland cool drink. Yuch.
Then I found an article on making strong coffee base with a french press and cold brewing. Normal hot coffee uses 10-15 grams to a cup of water so this is 2 to 3 times stronger. Cold brewing also reduces bitterness. I have been working on this recipe for months and here is my result. It is interesting how the type of coffee bean and roast changes the taste. A full city roast of Sumatra is one of my favorites.
Since releasing the recipe I had found an improvement. By adding two tablespoons of powered milk the smoothie stays creamier longer and tastes more milk shake like.
There are two parts that have to be prepared in advance: Cold Brewed Coffee Syrup and Sugar Syrup.
Cold Brewed Coffee Syrup
30 g ground coffee
1 1/4 cup cold water
- Place the ground coffee in the French Press.
- Pour in the cold water stirring with a wooden stir as you do.
- Put the top on pushing the plunger to the water line. This prevents the coffee from floating above the water.
- Place in the fridge
- Wait 8-24 hours
- Press plunger slowly to bottom
- Pour cold coffee in a storage container. It will keep in the fridge for a week.
Makes 1 cup of coffee syrup.
To make larger quantities of the coffee syrup:
125 gram to 1.25 litre water. Makes 1 litre
1 1/3 cup coffee to 1.25 US quart water. Makes 1 quart.
Sugar will not dissolve in cold water so we make a simple syrup.
1/2 cup granulated sugar
1/2 cup water
- Mix water with the sugar.
- If you want flavourings like vanilla add it now.
- Heat on stove and stir until the sugar is dissolved.
- Cool then bottle
Store the sugar syrup in the fridge.
Iced Coffee Smoothie
1/2 cup Cold Brewed Coffee Syrup
1 tbsp cold Sugar Syrup
2 tbsp powdered milk
1 1/4 cup cold milk
1 1/2 cup ice cubes
Optional: Flavouring such as chocolate. I like 1 tsp of Nesquik® (trademark owned by Nestlé)
- In a blender place Cold Brewed Coffee Syrup, milk and Sugar Syrup
- If any additional flavours or fruit are desired add them now.
- Add last ice cubes last to avoid melting
- Whip and pour
