Chorleywood bread process last requirement means that it is difficult to reproduce CBP in a small-scale kitchen. The CBP is only a method of producing quick-ripened bread dough. Large-scale bread-making with automated processes pre-dates the CBP by at least a century. Flour, water, yeast, salt, fat, and, where used, minor ingredients common to many bread-making techniques such as Vitamin C, emulsifiers and enzymes are mechanically mixed for about three minutes. The high-shear mixing generates high temperatures in the dough, which is cooled in some advanced mixers using a cooling jacket. Chilled water or ice may also be used to counteract the temperature rise
Bread and butter pudding can be used instead. Sometimes raspberry, strawberry, blackberry or mixed fruit jam, marmalade, or other sweet preserves will be spread upon the bread, along with the butter. Other modern variations include scattering fresh grapes between the layers of bread, melting apples into the egg-milk mixture, and using unusual types of breads — such as brioche — to make it. Lemon or orange peel will add a characteristic flavour. The earliest bread and butter puddings were called "whitepot" and used either bone marrow or butter. Whitepots could also be made using rice instead of bread, giving rise to the rice pudding
