murphy style
n.— «I ask this question in the Christmas section because you always see gift packs with coffee beans and it’s not instant coffee. And I am always worried that the gift receipient doesn’t have a coffee maker. Yes, you can make it “murphy style” or some refer to it as cowboy or camp side style. Just use the ground bean and a pot of water, bring to a boil and let the grounds settle.» —“Is it possible to make a cup of coffee from coffee beans (eg Starbucks) without a coffee maker?” Coffee Jan. 4, 2009.
