The simplest roasting method is to heat the nuts for about a minute in an open pan with holes. The easiest method to wet the shells is to heap the nuts into big piles and to use sprinklers intermittently. Moisture makes the kernel slightly rubbery and limits breakage of the kernels. Before the nuts are roasted they must be soaked in water-the moisture in the shell facilitates the rupturing of the cells containing shell oil and retaining it in the shell.
