Quick ship stainless steel double boilers are popular additions to many commercial kitchens. They are used in preparing delicate ingredients that are likely to separate or seize when prepared over direct heat like while tempering chocolate, keeping the gravy warm or while whisking up an egg-based sabayon. This technique does not require submerging in a hot water bath and is a popular stovetop cooking technique for large meals. Some of the quick ship stainless steel double boilers are available in various sizes ranging from 8 qts. to 20 qts. sizes. A major advantage is that you can get quick ship stainless steel double boilers in less than 24 hours from the time of order depending on product availability. They are also built to withstand the pressures found in many commercial kitchens offering top quality performance even after extensive use.
