In general terms, the products are snack chips, cakes and crackers made from food starch material. A quantity of the grain is puffed (expanded) in a manner which forms a snack product of considerable crispiness, lightness, and unique texture. According to a method of making the puffed food starch material product of the present invention, a puffing chamber is provided having inner surfaces and a chamber volume. A bulk amount of the food starch material is placed into the puffing chamber. The bulk amount of food starch material is caused to volumetrically expand. The expanding food starch material is constrained in its expansion in at least a first dimension while permitting expansion of the bulk amount in at least a second dimension.
