Hello All. The quote below is from the Guardian's page http://www.theguardian.com/lifeandstyle/wordofmouth/2014/may/08/how-to-make-perfect-malt-loaf-recipe, where the virtues of the malt loaf, along with a recipe, have been enumerated. "Though it's sold as a bread, it's definitely more in the cake category – the loaf bit is just there to justify the application of great wodges of salty butter, which is less of a serving suggestion and more of a three-line whip in my book." I am unable to picture a 'three-line whip': Is it a generous slice, with the three lines being, what? Is it in fact a reference to an actual whip (which I doubt very much it is)? Or is the author underlining some tip - what? - in order to emphasise it? Please help, and thanks in advance.
