Cooks have shared tips across the years. A hundred years ago Good Housekeeping magazine had a tips column called Discoveries. Readers could submit tips, and were paid one dollar for each tip that was used.
Here’s a tip for how to serve salads at a picnic:
When going on little picnic suppers – especially in a machine, where one eats by the roadside or in the car seat – individual paper drinking cups are most satisfactory as containers for salads. The salad may be packed in the individual paper cups and garnished attractively with a sprig of parsley in one side. They always call forth favorable comments and are not messy to handle and each person has his own portion easily handed out. – Mrs. R.H., D.C.
