INGREDIENTS: 1/2 a grapefruit wedged, 5-6 mint leaves
COST: About 33p a bottle
METHOD: Wedge or dice your grapefruit, ensuring it sits snuggly into your fruit chamber before adding in your mint leaves. The combination should have some room to breathe and allow water to pass through - so if your grapefruit is quite large - you may need to reduce quantities.
Grapefruit contains many nutrients (fibre, potassium, lycopene, vit c and choline) all combing to support a healthy heart. It has quite a strong flavour so adding mint calms it down a little and the water more drinkable.
