Universal coolers dough retarders. A dough retarder or pizza prep table is the perfect tool for any restaurant business working with dough. Dough Retarders come with or without marble tops. Marble tops are great for dough, as the smooth surface and hard material makes for the best dough material. Stainless steel tops on dough retarders and pizza prep tables will certainly get the job done. Dough retarders generally have a deeper prep area. Pizza prep tables generally have a refrigerated rail.
