To many the word "Tin" spells danger, and presents various complications, but the truth is that if the work is done carefully and thoroughly it is perfectly safe, whilst the process is equally simple when clearly understood as canning in glass jars. The secret of success is careful work in every particular, in filling and sealing the tins, and in sterilising them thoroughly during the process of cooking. One important factor to be borne in mind constantly, too, is the absolute necessity for perfect cleanliness right through the work, as it must be remembered that dirt or any foreign matter introduced into the tins means germs, which cause decay, and last, but not least, only perfectly sound and the best fruit should be used for canning.
