A common ingredient in baking and beer making, barley malt syrup, sometimes called barley malt extract, is used in cracker recipes to add a touch of sweetness (it’s half as sweet as sugar) and a rich, malt flavor. Made from barley that has been sprouted and roasted, barley malt syrup has the consistency of molasses and the flavor of a toasty, buttery grain. Eden makes my favorite barley malt syrup; find it with alternative sweeteners in natural grocery stores, or buy it online. Dark corn syrup can be used in a pinch, but it won’t provide the same butter flavor.
