Sense of Unity
It is such a waste for family heirloom recipes to be buried along with their creators. While many hold on to faded and smudged copies of written recipes, it would be best to pass the knowledge by having the older and younger generation cook together. This way, what is passed on is not limited to recipes as memories and experiences are also created.
Seal of Approval
The fact that a family heirloom recipe is passed on from generation to generation signifies the stamp of approval given by family members. It wouldn't endure that long if it did not carry the family seal of approval. Younger generations may sometimes try to modify the recipe to make it their own but the original will always have a special place.
More than the monetary value which a family heirloom recipe can represent, it is the sentimental value that families give more weight to. Its flavor and taste evokes nostalgia. It is that one food that will have its presence felt on dinner tables and family members could go on for hours telling stories about it.
