Upcycling External Salad Greens into Rich Mayonnaise – A Zero-Waste Recipe

Modeled after a popular New York eatery, this groundbreaking method transforms typically wasted outer salad leaves into an velvety herbaceous “mayonnaise”. It’s a smart way to minimize food waste while making a condiment delicious and versatile.

Why Repurpose External Salad Greens?

Although recycling produce scraps is a fundamental sustainable practice, finding creative applications for these parts is additionally beneficial.
