Ingredients :

• Prunes — Get d’Agen prunes if you can find them — they are softer and less acidic than generic versions. Soaking them overnight in cold water changes everything: they swell up, soften, and their flavor becomes rounder. Five prunes, no more, otherwise the taste becomes too dominant.
• Banana — It must be very ripe — with small brown spots on the skin, not just pale yellow. At this stage, the sugars have had time to develop and it smells like honey. A banana that is too green will give a floury taste that ruins the balance. Freeze it the night before if you want a colder, thicker smoothie.
• Chia seeds — One teaspoon is enough. They swell on contact with the milk during blending and provide that slightly thick texture that helps the smoothie hold up. No need to soak them separately — the blender does the work.
• Plant-based milk — Oat or almond milk works very well here. Avoid rice milk, which is too thin and would make the smoothie watery. Semi-skimmed cow’s milk also works perfectly if you don’t have intolerances.
