Transforming External Lettuce Leaves into Creamy Emulsion – A Zero-Waste Recipe

Drawing from a popular NYC restaurant, the innovative technique turns typically wasted outer lettuce leaves into a velvety herbaceous “mayonnaise”. It’s a smart approach to reduce kitchen waste while making a condiment delicious and versatile.

Why Use Outer Salad Leaves?

Those outer greens are the plant’s protective packaging, guarding the tender inner lettuce. While composting vegetable scraps is a basic sustainable habit, discovering new uses for these parts is additionally beneficial. Converting excess ingredients into fertile soil prevents landfill accumulation, where they may emit greenhouse gases, a potent climate concern.

It’s quite innovative if you think about it: produce rots and becomes the perfect growing medium to feed further plants, thereby closing the cycle and respecting the process of life.

Yet, with more than 30% extra produce getting produced than needed, using precious ingredients efficiently is essential. Minimizing leftovers not only conserves money but also promotes a more sustainable way of living.

The Green Emulsion Method

This versatile formula functions with any type of lettuce and nuts. By using a entire egg, one eliminate the hassle to use up an leftover white. This result is an smooth, nutty dressing that works beautifully with greens, roasted vegetables, seared poultry, noodles, or rice.

Serves two

For the Green Emulsion (Yields about 200g)

  • 100g butter
  • 50 grams external lettuce leaves from two romaine or butter lettuce, rinsed and dried
  • 20g shelled salted nuts – light-colored seeds like blanched almonds help keep the vivid green, but any seeds will do
  • 1 small entire egg

To Make the Salad

  • 2 romaine or butter lettuces, split longwise
  • Extra-virgin olive oil, to taste
  • Fresh lime juice or white-wine vinegar, to taste
  • 1 generous handful soft herbs (such as parsley), leaves left intact, stems thinly chopped

Instructions

Begin by preparing the mayonnaise. Melt the fat in a medium saucepan, add the external lettuce greens, place a lid and cook for approximately 60 seconds, stirring once or twice, until they’ve wilted. Transfer the contents into the jug of an stick processor, include the pistachios and egg, then blend until smooth. As necessary, incorporate more nuts to achieve a mayonnaise-like texture. Store in a airtight jar in the fridge for as long as three days.

To prepare the dish, sprinkle each gem portion with olive oil and lemon juice, then salt liberally. Coat with one zigzag pattern of the herb emulsion, then top with the herbs. Arrange on two plates and enjoy immediately.
