Sugar is eaten too often in our country, but it is valuable for preserving food and as a baking ingredient. Add other sweeteners that your family enjoys such as honey, molasses, and maple syrup.
Versatility, nutrition and your family's preferences should be your focus when choosing the basics for your pantry. I haven't mention the dried and canned fruits and vegetables you may want to store. Or the dried dairy products most families can use. You know your family the better than anyone. Develop a pantry well stored with the ingredients that will allow you to prepare meals you all will enjoy and thrive on.
