Novel viscosity stable corrugating adhesives having a carrier portion, e.g., cooked starch paste or a cooked flour paste having similar viscosity and flow characteristics, and a slurry portion containing flour having a particle size less than 100 mesh, and containing from 0.25 - 1.8 borax and 0.5 - 3.0 caustic, calculated on total solids, in amounts sufficient to provide the requisite initial tack and desired gel point to the adhesive but less than that which renders the adhesives viscosity unstable.
