Upcycling External Lettuce Greens into Creamy Emulsion – A Zero-Waste Guide

Inspired by a well-known NYC eatery, this groundbreaking method turns usually thrown-out outer lettuce greens into an luxurious herbaceous emulsion. It’s a ingenious way to minimize kitchen waste while producing something delicious and versatile.

The Reason Use External Salad Leaves?

Those external greens are nature’s protective wrapping, guarding the delicate inner lettuce. While composting produce scraps is a fundamental zero-waste habit, finding creative uses for these parts is additionally impactful. Converting surplus food into fertile compost avoids dump buildup, where they can release methane, which is a potent environmental issue.

It’s quite radical when you think about it: food rots and transforms into that ideal growing medium to feed further plants, thereby closing the cycle and honoring nature’s process of growth.

Yet, given over 30% extra food getting produced than required, using precious resources efficiently becomes crucial. Reducing leftovers not only conserves cash but also supports a more sustainable lifestyle.

This Herb-Infused “Mayonnaise” Recipe

The adaptable formula functions with whatever type of salad greens and nuts. By incorporating one whole egg, one eliminate any hassle to use up the leftover white. This outcome is a smooth, rich sauce that pairs beautifully with greens, roasted veggies, seared chicken, pasta, or grains.

Yields 2

To Make the Herb Emulsion (Yields approximately 200 grams)

• 100g butter
• 50g external salad greens of two romaine or butter lettuce, rinsed and dried
• 20 grams peeled salted nuts – light-colored seeds such as blanched almonds help maintain a vivid color, though any seeds can do
• 1 medium whole egg

To Make the Salad

• 2 romaine or butter heads, halved longwise
• Cold-pressed oil, to taste
• Fresh lime juice or apple cider vinegar, as desired
• One generous bunch soft greens (like dill), leaves left whole, stems thinly minced

Steps

Begin by preparing the mayonnaise. Melt the fat in a small pot, add the external salad leaves, place a lid and wilt for about a minute, stirring a couple times, until they’ve softened. Transfer the contents into the container of an immersion blender, include the nuts and egg, then process until smooth. If needed, add more nuts to achieve a thick texture. Store in a airtight container in the fridge for as long as 3 days.

To assemble the salad, sprinkle each gem half with olive oil and lemon juice, then salt generously. Dress with a tight drizzle of the green mayonnaise, then scatter with the herbs. Arrange on 2 plates and enjoy immediately.
