Cold-brewed Iced Coffee

I had this saved in my bookmarks for ages and it's finally been hot enough to actually prefer iced coffee over ordinary coffee. This cold-brewed idea is easier and does indeed taste better than using cooled espresso.

Cold-brewed iced coffee

1/3 cup ground coffee
1 1/2 cups water
milk, optional
ice, to serve

Mix coffee and water and leave for 12 hrs or overnight. Strain well and serve with ice and milk as desired.
