Habbitree’s pages say to prepare a Daily Nutrition Mix with 30 g of powder in 200 ml of milk. Turning it into a smoothie is a variation, offered as an idea and not a tested recipe.
Add 30 g of the mix and 200 ml of cold milk to a blender.
Add half a banana or a few pieces of fruit.
Blend until smooth.
The label figures cover the powder only. The milk and fruit add their own calories, sugars and protein. If you want to keep sugar low, the No Added Sugar Almond Kulfi flavour lists 0 g added sugar per serving. All four flavours contain tree nuts.
