Ingredients :

• Fresh mint — Use classic spearmint, not peppermint which is too aggressive in a cold drink. Whether from a supermarket bunch or a balcony pot, both work. The simple test: rub a leaf between your fingers, the scent should be sharp and immediate.
• Fresh lemons — Two or three depending on their size. Avoid lemons that look dried out or too hard — they give little juice and a lot of bitterness. A good lemon feels slightly soft under thumb pressure.
• Honey — Optional, but if you use it, choose something neutral and liquid — acacia honey dissolves well in cold water. Chestnut honey will overpower the mint and lemon, which is a shame.
• Cold water — Very cold, from the fridge or filtered. Not sparkling here — the bubbles don’t mix well with blending and you lose the lightness of the result.
