Use the Linden Sweden Notched Rolling Pin to score rye or oat breads for knÃ¤ckebrÃ¶ds, or Swedish hardtack. The notches restrict the bread from rising, making it easy to store - but even better, it creates a flat, bread thatâ€™s excellent for dipping or topping. Hardtack is more like a cracker than bread, and is often healthier than store-bought alternatives. This rolling pin makes quick work of dough, notching an area 25.4cm across in one pass. A recipe for traditional Swedish hardtack is included with this rolling pin.
