We use the system from Toddy Cafe where you put a pound of ground coffee in a plastic tub with a filter and a drain at the bottom. You add 9 cups of cold water and let it sit for 10-12 hours. After that you drain out a whole carafe of coffee syrup which you keep in the fridge. You make coffee by adding 3 parts water to 1 part syrup. We don't waste any syrup and the coffee is never sitting on a burner getting cooked to death. But the best part is, the syrup is not at all acid because it's heat that leaches acidity from coffee beans. If coffee upsets your tummy, this the way to go!
Although I have to say this is not what I would call a writer's block kind of question. This is more of a poll and less of a chance to ruminate on something thoughtful, like holiday traditions or life experiences.
