My Dad, who accompanied me on my first trip to Guatemala, also came home completely hooked on this new method of making coffee. Previously, he would drink his coffee with cream and sugar, but now switched to only sugar, since the coffee tasted so much better.
He brought home a little pot, and Mom would now make their coffee this way all the time. She would also make a lot of the essence, a bit at a time, and filled a little jar with it. Dad would take this with him to work, and by adding some of the essence and hot water, could have a great cup of coffee at work also.
