I take a big mug for my brew. boil water in a kettle, fill up my mug with boiling water. I then add a large spoonful of instant coffee. Then I take a large spoonful of local ground coffee from here in Nicaragua and put that into the cup of instant. After a while the ground coffee will become water logged and sink to the bottom. This is like blending tobacco. Warning! Don't try this before bed time. Warning! Don't don't drink the last inch of coffee.
