Why was the development of Sanskrit important to making vadas last?

There seems to be a misunderstanding in your question. The development of Sanskrit, an ancient Indian language, is not directly related to the preservation of vadas, a type of Indian snack.

Here's why:

* Sanskrit and Language: Sanskrit is a classical language primarily used for religious texts, philosophy, and literature. While it influenced many Indian languages, it wasn't the primary language for everyday use or culinary practices.

* Vadas and Culinary Tradition: Vadas are a popular snack across various regions of India, and their longevity is primarily due to:

* Popularity and Taste: They are delicious and versatile, adapting to different tastes and ingredients across regions.

* Simple Ingredients: Vadas often use basic, readily available ingredients, making them easy to prepare.

* Preservation Techniques: While not as common for vadas, some preservation techniques like pickling or drying might have helped extend their shelf life in the past.

Therefore, the development of Sanskrit had no direct influence on the longevity of vadas. It's likely a case of mistaken connection.
