This is the basic Scottish shortbread recipe. The cornflour improves the crumbly texture which is part of the tradition. You can add chocolate, raisins and nuts if you want.
Light texture and nice small mix, rather than many of the other recipes that have 4-5 cups of flour in their recipes. - 23 Mar 2014
Was my first time making shortbread and it came out great. Really easy to do. However I think I'll make twice the amount next time, as it didn't last long. - 13 Nov 2011 (Review from Allrecipes UK & Ireland)
Very crumbly, taste excellent. Puts store-bought in the shade! Recommend doubling the quantity, though - disappears too fast to go around! - 07 Dec 2010 (Review from Allrecipes UK & Ireland)
