Transforming External Salad Leaves into Creamy Mayonnaise – A Zero-Waste Recipe

Modeled after an acclaimed New York restaurant, the innovative method converts often-discarded outer lettuce greens into an luxurious herbaceous emulsion. It’s an ingenious way to minimize food waste while creating something flavorful and flexible.

The Reason Repurpose Outer Lettuce Leaves?

These external greens are nature’s protective packaging, shielding the delicate inside lettuce. While composting vegetable scraps is one basic zero-waste practice, discovering new uses for them is additionally impactful. Turning excess ingredients into rich soil prevents dump accumulation, where it may release methane, a potent climate issue.

It’s quite innovative if you consider about it: food decomposes and transforms into that perfect soil to feed more crops, thus completing the loop and respecting the process of life.

Yet, given over 30% surplus food getting made than required, using valuable ingredients wisely is essential. Reducing leftovers not only saves money but also supports the increasingly sustainable lifestyle.

The Herb-Infused Emulsion Method

This versatile formula works with whatever variety of salad greens and seeds. By incorporating one entire egg, you avoid the need to repurpose an extra egg white. This result is a smooth, rich sauce that works beautifully with greens, roasted vegetables, seared chicken, pasta, or grains.

Yields 2

To Make the Herb Emulsion (Makes about 200 grams)

  • 100 grams butter
  • 50 grams outer salad greens from 2 little gems, washed and dried
  • 20 grams peeled salted pistachios – light-colored seeds such as cashews help maintain a vivid green, but any seeds can do
  • One medium whole egg

To Make the Salad

  • 2 romaine or butter heads, split lengthways
  • Cold-pressed oil, as needed
  • Fresh lime juice or white-wine vinegar, to taste
  • One small bunch fresh herbs (such as chervil), sprigs left intact, stems finely chopped

Steps

First making the emulsion. Heat the fat in one medium pot, add the external lettuce leaves, place a lid and wilt for about 60 seconds, stirring a couple times, till they have wilted. Pour the mixture into a container of an stick processor, add the pistachios and egg, then blend till creamy. If needed, incorporate more seeds to achieve the thick consistency. Store in an sealed container in the refrigerator for as long as 3 days.

To assemble the dish, sprinkle each gem half with olive oil and acid, then salt generously. Coat with one zigzag pattern of the herb mayonnaise, then top with the greens. Place on two dishes and enjoy immediately.
