Why are julienne vegetables really important for spring rolls?

While julienned vegetables can enhance the presentation and texture of spring rolls, they are not strictly essential. Spring roll recipes can vary greatly, and not all fillings require vegetables to be cut in a specific way. Some recipes may call for minced, chopped, or even whole leaves depending on the desired outcome and regional preferences. So while julienned vegetables can add a visually appealing touch, they are not considered a key component or requirement for spring rolls.
