so much in the saving of time, fuel and energy in effecting 

 a complete sterlization of the food products. 



4. Steam-pressure outfits. This type of canner 

 is manufactured so as to carry from five to thirty pounds 

 of steam pressure and is equipped with vat, crate, cover, 

 thermometer or pressure gauge, safety valve and steam 

 pet-cock. The safety valve can be easily regulated so as to 

 carry different pressure values and thus accommodate the 

 needs of various vegetables and food products. 



5. Aluminum pressure-cookers. This is a combina- 

 tion outfit, which is used for both general cooking purposes 

 and the canning of fruits, vegetables and meats. Because 

 of its general utility in the home, for the cooking of all 

 kinds of meats, vegetables, soups, gravies and stews, it can 

 be made to be of great labor-saving value to the housewife. 

 It is considered the fastest canning outfit on the market. 

 This is due to the fact that it is made entirely of aluminum 

 and transmits heat very quickly and will carry as high as 

 thirty pounds of steam pressure. Its makeup and necessary 

 parts are practically the same as in the all steam-pressure 

 outfits. 



Note. The time scheduled for sterilization given in all 

 of our recipes is made to accommodate the four distinct 

 types of home canners. The home-made outfits and hot- 

 water commercial outfits are classed in the first place and 

 under the head of "Hot-water bath outfits." The other 

 three are classed in the order given above and under the 

 same names, thus making the four classes with different 

 time requirements. In using the vacuum seal jars an air 

 pump is used for sealing; aside from this you can follow 

 same steps in packing, blanching, adding sirup, water and 

 salt but substitute the vacuum pressure for part of time 

 for the final cooking period. With fruits it will be neces- 

 sary to sterilize fruit enough for table use before sealing.
