My recipe for coffee-
1-Take coffee powder double quantity than what normal people use.
2-Half the sugar as you like to prefer (i like less sugar in hot coffee and in cold coffee i prefer double the quantity of sugar)
3-Take 2 spoon of water and and blend the coffee and sugar until the sugar get dissolved and start getting foam.
4- Add the water or milk (hot or cold as you want).
Some people boil the coffee with water or milk which can makes the coffee taste worse.
