flour gold
n.— «You can find nuggets. California is renowned for having larger pieces. But primarily what you’re going to find at first is fine gold, or flour gold as they call it. That’s all worth money too. Don’t throw it out, or be frustrated or disgusted by it if that’s all you find. You’d be shocked to find out how little it takes to make a full ounce of gold.» —“California?s Second Gold Rush?” KCBS-AM (San Francisco, California) Mar. 16, 2008. (source: Double-Tongued Dictionary)
