Upcycling External Lettuce Leaves into Rich Emulsion – An Sustainable Recipe

Drawing from a popular New York restaurant, this creative technique converts typically wasted external salad leaves into an smooth herbaceous emulsion. This is a ingenious approach to cut down on food waste while making something flavorful and versatile.

Why Use External Salad Greens?

Those outer greens serve as nature’s natural packaging, guarding the delicate inner leaves. While recycling produce scraps is one fundamental zero-waste practice, finding creative uses for them is even more beneficial. Turning excess food into fertile compost avoids landfill buildup, where they can emit greenhouse gases, which is a potent climate concern.

This is quite radical when you think about it: food decomposes and transforms into the ideal growing medium to feed more plants, thus completing this loop and respecting the cycle of growth.

Yet, with over 30% extra food being made compared to required, consuming precious ingredients efficiently becomes crucial. Minimizing waste not only conserves cash but also promotes the increasingly sustainable lifestyle.

The Herb-Infused Emulsion Method

This versatile formula functions with any type of lettuce and nuts. Through incorporating one entire egg, one eliminate the hassle to use up the extra egg white. This outcome is an smooth, rich dressing that pairs perfectly with greens, roasted veggies, seared poultry, noodles, or grains.

Yields 2

To Make the Green “Mayonnaise” (Makes about 200g)

• 100 grams unsalted butter
• 50 grams external salad leaves from 2 romaine or butter lettuce, rinsed and dried
• 20 grams peeled salted nuts – light-colored nuts like pine nuts help maintain the bright color, though any seeds will do
• One small entire egg

To Make the Salad

• Two romaine or butter lettuces, split lengthways
• Cold-pressed olive oil, to taste
• Fresh lime juice or apple cider vinegar, to taste
• 1 generous handful soft greens (such as parsley), leaves left whole, stems thinly chopped

Steps

Begin by making the emulsion. Heat the fat in one small pot, add the external salad greens, cover and wilt for about 60 seconds, stirring once or twice, until they have wilted. Pour the mixture into a container of a immersion processor, add the pistachios and whole egg, then process till smooth. If needed, add more nuts to get a mayonnaise-like consistency. Store in a airtight jar in the fridge for up to three days.

For prepare the salad, drizzle each gem half with olive oil and acid, then season liberally. Coat with a tight pattern of the green emulsion, then scatter with the greens. Place on two plates and enjoy immediately.
