Abstract: The invention relates to a process for making a thin biscuit having a smooth surface, including mixing ingredients at a temperature between 37° C. and 70° C. to obtain a sheetable cohesive dough. The dough includes 0-56% wheat flour, 4-62% native starch, and 1-26% pre-gelatinised starch. For one unit of weight of native starch NS, pre-gelatinised starch PS, and wheat flour WF, i.e. with NS+PS+WF=1, WF?0.8, PS?0.37 and 0.7?NS/PS?9. The dough also includes 5-18% water, 2-12% fat, 0-28% sugar; 0-8% whey powder, and 0%-0.5% salt, but devoid of a leavening agent. The process also includes sheeting the dough to a thickness between 0.2 and 1 mm; cutting the sheeted dough into dough pieces; and baking the dough pieces on a perforated support to obtain a thin biscuit that is devoid of blisters.
