For one generous serving
Use 1 ripe banana, 250 ml cold pasteurized milk or a suitable unsweetened milk alternative, and an optional pinch of cinnamon. A very ripe banana usually needs no added sugar.
Blend until smooth
Peel and slice the banana. Add it to the blender with the milk and blend until smooth. Add a little more milk if you prefer a thinner texture.
Serve straight away
Pour into a glass and add cinnamon if you like. The texture and color change as the drink stands, so make it close to serving. Check the milk label if you need to avoid a particular allergen.
