Detailed Description (Procedure)

Fruit Preparation: Chop the strawberries and the banana. If you want a "frappé"-style texture, you can use frozen strawberries.
Cup Capacity: Place the fruit in the blender jar and add the cold milk or plant-based drink.
Technical Incorporation: Add the Stevia 1:8, the pinch of Bonsalt 0% Sodium and the Cream of Tartar. Castelló Cream of Tartar is essential here to prevent the acidity of the strawberry from "curdling" the milk protein, maintaining a smooth and silky texture.
Processed: Beat at high speed for 45-60 seconds until the mixture is completely smooth and takes on an even pink color.
Service: Serve immediately in tall glasses decorated with a slice of strawberry on the rim.

Long-Lasting Color: Thanks to the Cream of Tartar, the smoothie won’t darken if it takes you a few minutes to drink it, keeping that fresh, appetizing look.
