Ingredients :

• Fresh spinach — Bagged baby spinach is perfect for this. Avoid large leaves which can give an earthy, bitter aftertaste. Pick the ones that still smell like fresh grass when you open the bag — if it already smells old, the smoothie will taste like it.
• Cucumber — It provides volume and a watery freshness that thins everything out without adding weight. No need to peel if the skin is thin and smooth. The seeds inside disappear in the blender without a trace.
• Green apple — Granny Smith if you can find one. Its natural slight acidity balances the greens without masking them. An apple that’s too sweet would make the whole thing taste flat and a bit cloying.
• Lemon — The juice of one whole lemon, squeezed by hand directly into the blender. It seems like a lot, but it’s what gives the drink character. A regular supermarket lemon works fine — no need for organic for this.
