Repurposing Outer Salad Leaves into Creamy Mayonnaise – An Sustainable Recipe

Drawing from a popular NYC eatery, the creative method converts often-discarded external salad greens into an luxurious green emulsion. This is an ingenious approach to minimize food waste while making a condiment tasty and versatile.

Why Repurpose Outer Lettuce Greens?

These external greens are the plant’s protective packaging, shielding the tender inside leaves. While recycling vegetable scraps is one fundamental zero-waste practice, finding new applications for these parts is even more beneficial. Converting surplus ingredients into fertile soil prevents landfill buildup, where they may release methane, a powerful climate concern.

It’s quite innovative if you think about it: produce rots and transforms into that perfect soil to feed more plants, thus completing this loop and respecting the cycle of life.

However, with more than thirty percent surplus produce getting produced than required, consuming valuable resources wisely is essential. Minimizing leftovers not only conserves money but also promotes the increasingly sustainable way of living.

This Green Emulsion Method

This versatile recipe functions with any type of salad greens and nuts. Through using one whole egg, you avoid the need to repurpose the leftover egg white. The outcome is a creamy, nutty sauce that pairs beautifully with salads, grilled vegetables, seared chicken, pasta, or rice.

Serves two

For the Herb Emulsion (Makes approximately 200g)

  • 100g unsalted butter
  • 50g external lettuce greens of two romaine or butter lettuce, washed and dried
  • 20g peeled roasted nuts – light-colored nuts like cashews help keep a vivid green, but whatever nuts will work
  • 1 medium whole egg

To Make the Side

  • Two little gem lettuces, halved lengthways
  • Cold-pressed oil, as needed
  • Fresh lime juice or white-wine vinegar, to taste
  • One small handful fresh greens (like dill), leaves left intact, stems thinly chopped

Instructions

Begin by preparing the emulsion. Melt the butter in one medium saucepan, toss in the outer lettuce greens, cover and wilt for approximately a minute, mixing a couple times, until they’ve wilted. Pour this mixture into the container of an immersion blender, include the nuts and whole egg, then process until smooth. If needed, incorporate extra nuts to get a thick texture. Store in an sealed jar in the refrigerator for up to 3 days.

For prepare the salad, drizzle each gem portion with olive oil and acid, then salt generously. Coat with one tight pattern of the green emulsion, then scatter with the greens. Arrange on two plates and serve immediately.
