Ingredients :

• Fresh spinach — Choose fresh bagged or loose spinach — not frozen, which releases too much water and gives a slimy mouthfeel. A tightly packed handful in your palm is the right dose. If they are a bit wilted, run them under cold water for two minutes; they’ll spring back to life.
• Cucumber — Keep the skin if your cucumber is organic or well-washed — it adds color and extra fiber. Half is enough. No need to slice it thinly; the blender handles large chunks just fine.
• Green apple (Granny Smith preferred) — Granny Smith is the right choice here. Its natural acidity balances the earthy taste of the spinach, and its pectin helps transit. Avoid overly sweet apples like Golden Delicious — they overpower everything else and the balance is lost.
• Lemon with the skin — Yes, with the skin — but only if your lemon is untreated. The zest contains essential oils that really scent the smoothie, adding a slightly bitter and aromatic note that makes all the difference. Otherwise, just the juice works very well too.
