In making every kind of jam it is essential the fruit should be picked dry.

It is also a time-honoured tradition that the fruit is best picked when basking in the morning sun.
It is also necessary that the fruit should be free from dust, and that all decayed or rotten fruit should be carefully picked out.
Jam is made by boiling the fruit with sugar, and it is false economy to get common sugar; cheap sugar throws up a quantity of scum.

Years back many persons used brown sugar, but in the present day the difference in the price of brown and white sugar is so trifling that the latter should always be used for the purpose.

The sugar should not be crushed.

It is best to boil the fruit before adding the sugar.
