Drawing from a popular NYC eatery, the innovative technique transforms often-discarded outer lettuce greens into a luxurious green “mayonnaise”. It’s a ingenious approach to minimize kitchen waste while creating a condiment delicious and adaptable.

Why Repurpose Outer Salad Greens?

These external greens are nature’s protective wrapping, guarding the tender inside lettuce. Although recycling produce scraps is a basic sustainable practice, finding creative uses for these parts is additionally beneficial. Converting surplus food into rich compost prevents landfill buildup, where they may release methane, which is a powerful climate issue.

It’s rather radical if you think about it: food rots and transforms into that perfect growing medium to feed further crops, thus completing the cycle and honoring the process of growth.

Yet, with more than 30% extra food being made compared to needed, using valuable ingredients wisely becomes essential. Minimizing leftovers not only saves money but also promotes the increasingly eco-friendly way of living.

This Green “Mayonnaise” Method

This adaptable formula works with whatever type of lettuce and nuts. Through incorporating a whole egg, you eliminate the need to use up an extra egg white. The result is a smooth, nutty sauce that pairs beautifully with greens, roasted vegetables, grilled poultry, pasta, or grains.

Serves 2

To Make the Green Emulsion (Yields about 200 grams)

• 100g unsalted butter
• 50g external salad greens of 2 romaine or butter lettuce, washed and dried
• 20g shelled roasted pistachios – light-colored seeds such as pine nuts help maintain a vivid green, though any seeds can do
• 1 small entire egg

For the Side

• Two romaine or butter lettuces, split lengthways
• Cold-pressed oil, as needed
• Fresh lime juice or white-wine vinegar, as desired
• 1 small handful fresh herbs (such as parsley), sprigs picked whole, stems thinly minced

Steps

Begin by preparing the emulsion. Heat the fat in a medium pot, toss in the outer salad leaves, place a lid and wilt for approximately a minute, mixing a couple times, till they have wilted. Transfer this mixture into the jug of a stick blender, include the nuts and egg, then process until smooth. If needed, add extra seeds to achieve a thick consistency. Store in an sealed container in the fridge for as long as 3 days.

For assemble the salad, drizzle each lettuce half with olive oil and lemon juice, then season liberally. Dress with a tight pattern of the green mayonnaise, then scatter with the greens. Place on 2 dishes and enjoy immediately.
