Transforming External Salad Greens into Rich Mayonnaise – A Zero-Waste Guide

Inspired by an acclaimed NYC restaurant, this groundbreaking technique converts usually thrown-out outer lettuce leaves into an velvety herbaceous “mayonnaise”. This is a ingenious way to cut down on food waste while producing a condiment delicious and versatile.

Why Use Outer Lettuce Leaves?

These external greens serve as nature’s natural wrapping, guarding the tender inside lettuce. While composting produce scraps is a fundamental sustainable habit, finding new uses for these parts is even more impactful. Turning surplus food into rich compost avoids dump accumulation, where they may release greenhouse gases, a powerful climate concern.

It’s quite innovative when you think over it: produce rots and becomes that perfect growing medium to nourish further plants, thus completing the loop and respecting the process of growth.

However, given more than 30% extra food being made than needed, consuming valuable ingredients wisely is essential. Minimizing leftovers not only conserves cash but also supports a more eco-friendly way of living.

The Green “Mayonnaise” Method

This versatile formula works with whatever type of lettuce and seeds. By using one whole egg, one eliminate the hassle to repurpose the leftover white. This result is a creamy, rich dressing that works beautifully with salads, grilled veggies, grilled chicken, pasta, or rice.

Serves two

To Make the Herb Emulsion (Makes approximately 200 grams)

• 100 grams unsalted butter
• 50g external lettuce greens from 2 romaine or butter lettuce, washed and thoroughly dried
• 20g peeled salted pistachios – light-colored nuts such as cashews help keep a bright color, though any seeds can do
• 1 medium entire egg

To Make the Side

• 2 romaine or butter heads, split lengthways
• Cold-pressed olive oil, as needed
• Lemon juice or white-wine vinegar, to taste
• 1 generous bunch fresh greens (like chives), sprigs left whole, stalks thinly minced

Steps

First preparing the emulsion. Heat the fat in a small pot, toss in the outer lettuce greens, place a lid and cook for approximately a minute, mixing a couple times, till they’ve wilted. Pour the mixture into a jug of a immersion blender, add the pistachios and whole egg, then blend until creamy. As necessary, add more seeds to achieve a thick consistency. Store in an sealed jar in the refrigerator for as long as three days.

For prepare the salad, drizzle each gem half with oil and acid, then season generously. Dress with a zigzag pattern of the green emulsion, then scatter with the greens. Arrange on two dishes and enjoy immediately.
