Unfortunately there exists a very unreasonable prejudice on the part of many persons against all kinds of provisions that are preserved in tins.  This prejudice is kept alive by stories that occasionally get into print about families being poisoned by using tinned goods.  We hear stories also of poisoning resulting from using copper vessels.  Housekeepers should endeavour to grasp the idea that the evil is the result of their own ignorance, and that no danger would accrue were they possessed of a little more elementary knowledge of chemistry.  If a penny be dipped in vinegar and exposed to the air, and is then licked by a child, a certain amount of ill effect would undoubtedly ensue, but it does not follow that we should give up the use of copper money.  So, too, if we use tinned goods, and owing to our own carelessness or ignorance find occasionally that evil results ensue, we should not give up the use of the goods in question, but endeavour to find out the cause why these evil results follow only occasionally.

All good cooks know, or ought to know, that if they leave the soup all night in a saucepan the soup is spoilt.  Again, all housekeepers know that although they have a metal tank, they are bound to have a wooden lid on top, there being a law to this effect.  The point they forget in using tinned goods is this, so long as the air is excluded from the interior of the tin no chemical action goes on whatever.  When, therefore, they open the tin, if they turn out the contents at once no harm can ensue.  Unfortunately, there are many thousands who will open a tin, take out what they want, and leave the remainder in the tin.  Of course, they have only themselves to blame should evil result.

Preserved vegetables are so useful that they are inseparable from civilised cookery; for instance, what would a French cook do were he dependent for his mushrooms upon these fresh grown in the fields?  The standard dish at vegetarian restaurants is mushroom pie, and, thanks to tinned mushrooms, we can obtain this dish all the year round.  In most restaurants peas are on the bill of fare throughout the year.  Were we dependent upon fresh grown ones, this popular dish would be confined almost to a few weeks.

In the case of preserved goods, tinned fruits are even more valuable than tinned vegetables.  Ripe apricots and peaches picked fresh from the tree are expensive luxuries that in this country can only be indulged in by the rich, whereas, thanks to the art of preserving, we are enabled to enjoy them all the year round.  We will run briefly through a few of the chief vegetables and fruits, and give a few hints how to best use them.  First of all—­

ASPARAGUS, TINNED.—­Place the tin in the saucepan with sufficient cold water to cover it.  Bring the water to a boil and let it boil for five minutes; take out the tin and cut it open round the edge, as near to the edge as possible, otherwise you will be apt to break the asparagus in turning it out.  Drain off the liquor and serve the asparagus on freshly made hot toast.  There is much less waste as a rule in tinned asparagus than in that freshly cut.  As a rule, you can eat nearly the whole of it.
