Upcycling External Lettuce Greens into Creamy Emulsion – A Sustainable Guide

Drawing from a well-known New York eatery, this groundbreaking technique turns usually thrown-out external lettuce leaves into an velvety green “mayonnaise”. It’s an ingenious approach to reduce kitchen waste while making something flavorful and flexible.

The Reason Repurpose Outer Lettuce Leaves?

These outer leaves are nature’s protective packaging, shielding the delicate inner lettuce. While recycling vegetable scraps is a basic sustainable practice, discovering creative applications for them is additionally impactful. Turning surplus ingredients into rich soil prevents landfill buildup, where they can emit greenhouse gases, which is a powerful environmental concern.

It’s rather innovative if you think over it: food rots and transforms into that perfect growing medium to nourish more plants, thereby completing this cycle and honoring the process of growth.

However, given over 30% extra food getting made than needed, using valuable resources efficiently becomes essential. Minimizing leftovers not only conserves cash but also supports a increasingly sustainable way of living.

The Herb-Infused Emulsion Recipe

This versatile recipe works with any variety of lettuce and seeds. Through incorporating one entire egg, you avoid any hassle to use up the extra white. This outcome is a creamy, nutty dressing that pairs beautifully with salads, grilled vegetables, seared poultry, noodles, or rice.

Serves two

To Make the Green “Mayonnaise” (Yields approximately 200 grams)

  • 100 grams butter
  • 50g external lettuce leaves from two romaine or butter lettuce, rinsed and thoroughly dried
  • 20g peeled salted pistachios – white seeds like cashews assist keep a vivid color, but any seeds can do
  • 1 medium whole egg

For the Salad

  • 2 romaine or butter heads, split longwise
  • Cold-pressed oil, to taste
  • Lemon juice or apple cider vinegar, as desired
  • 1 generous handful soft greens (like chervil), sprigs picked whole, stems thinly minced

Steps

Begin by making the emulsion. Heat the fat in a medium pot, toss in the external salad greens, place a lid and wilt for approximately a minute, mixing a couple times, till they’ve softened. Transfer the mixture into the container of a immersion processor, include the pistachios and whole egg, then process until smooth. As necessary, incorporate extra seeds to achieve a mayonnaise-like consistency. Keep in an airtight jar in the fridge for as long as 3 days.

To prepare the salad, sprinkle each gem half with oil and lemon juice, then salt liberally. Coat with one tight drizzle of the herb emulsion, then scatter with the greens. Arrange on 2 plates and serve immediately.
