process of preparing a dry , instant , wheat or farina - like product in flake form which will readily rehydrate upon the addition of hot water . farina and an effective amount of guar gum in powder form are admixed . the homogeneous mixture is impregnated with a sufficient amount of water to saturate the mixture . the mixture is tempered , preferably with agitation , to produce a material having uniform moisture . the tempered material is cooked , the average particle size of the cooked material being increased thereby . the average particle size of the cooked material is then reduced . the particulate , cooked material is dried . the dry , particulate material is then tempered to provide a uniform moisture content . the tempered , particulate material is flaked to form a dry product in flake form , which is capable of being readily rehydrated by the addition thereto of hot water to provide a food product having the texture , etc ., of cooked farina .
