As it's extensively hot, I am just practically living on water, for a change drinking juices with sugar is not healthy too... Here is a drink without sugar and it's a perfect, energetic and healthy summer drink for you from my kitchen.
For a glass..
2 tbsp dried Cranberries
1 tbsp dried Blue Berries
Few Mint leaves
2 tbsp or more Honey as per your requirement..
1 cup Water
Pinch of Salt
2 tbsp Lime juice
1 cup Leaker Tea ( Take a cup of hot water, add 1/4 tsp of tea leaves. Cover and keep for 2 minutes. Strain it.)
Take a pot. Add water, strawberries, cranberries, blue berries, few mint leaves and pinch of salt. Simmer it on medium heat till it reduces to 1/2 it's quantity. Cool it. Take a blender. Add the berry and mint decoction, leaker tea, honey, lime juice and ice. Blend it well. Pour it into a glass and enjoy the perfect, healthy and energetic drink.
P. S. You can also use fresh berries, if it is available.
