Repurposing External Lettuce Leaves into Creamy Emulsion – A Zero-Waste Guide

Inspired by a popular NYC eatery, the groundbreaking technique transforms often-discarded external lettuce greens into an velvety green emulsion. This is a brilliant way to reduce food waste while creating a condiment delicious and versatile.

The Reason Use External Salad Greens?

These external greens are nature’s protective wrapping, guarding the delicate inner leaves. Although recycling produce trimmings is a basic sustainable practice, discovering new applications for these parts is additionally impactful. Turning surplus food into fertile soil prevents landfill buildup, where they can emit greenhouse gases, a powerful climate issue.

It’s rather radical if you think about it: produce decomposes and transforms into the ideal growing medium to feed further plants, thus closing the cycle and honoring nature’s process of growth.

Yet, with over thirty percent surplus produce getting produced compared to required, consuming valuable resources wisely becomes crucial. Minimizing waste not only saves money but also promotes the increasingly eco-friendly way of living.

The Herb-Infused Emulsion Method

The versatile formula works with whatever type of lettuce and seeds. By using one whole egg, you avoid the need to use up an extra white. The outcome is an creamy, nutty dressing that works beautifully with greens, roasted veggies, grilled chicken, noodles, or grains.

Serves two

For the Herb Emulsion (Makes approximately 200 grams)

  • 100 grams unsalted butter
  • 50g outer lettuce greens of two romaine or butter lettuce, washed and thoroughly dried
  • 20g shelled roasted pistachios – light-colored seeds such as pine nuts help maintain the vivid green, but any seeds will do
  • One small whole egg

To Make the Side

  • Two little gem heads, split lengthways
  • Extra-virgin olive oil, as needed
  • Lemon juice or white-wine vinegar, as desired
  • 1 small bunch fresh herbs (such as chives), leaves left whole, stalks finely minced

Steps

First preparing the emulsion. Melt the butter in a medium saucepan, toss in the external lettuce leaves, place a lid and wilt for approximately 60 seconds, stirring a couple times, till they’ve wilted. Pour the contents into the container of an immersion blender, add the pistachios and whole egg, then blend until smooth. As necessary, add more nuts to achieve the mayonnaise-like texture. Keep in an airtight container in the fridge for up to 3 days.

For prepare the salad, sprinkle each gem half with olive oil and lemon juice, then salt generously. Dress with one zigzag drizzle of the green mayonnaise, then scatter with the herbs. Arrange on two dishes and serve immediately.
