Drawing from a well-known NYC eatery, this groundbreaking technique turns often-discarded external lettuce greens into a velvety herbaceous emulsion. It’s an brilliant approach to reduce leftovers while creating a condiment flavorful and flexible.

The Reason Use Outer Salad Greens?

These external leaves serve as nature’s natural wrapping, guarding the tender inside lettuce. Although composting produce scraps is one basic zero-waste habit, finding new uses for these parts is even more impactful. Converting excess food into fertile compost avoids landfill buildup, where it can release greenhouse gases, which is a potent environmental issue.

This is quite innovative if you think about it: food decomposes and transforms into that perfect soil to nourish further plants, thereby closing the loop and honoring nature’s process of growth.

Yet, given over thirty percent surplus food being made compared to needed, consuming precious resources wisely is crucial. Minimizing waste not only conserves cash but also promotes a more sustainable lifestyle.

The Green “Mayonnaise” Recipe

This adaptable recipe functions with any variety of lettuce and seeds. By incorporating one whole egg, you avoid any need to repurpose the extra white. The outcome is a smooth, nutty dressing that works beautifully with salads, roasted vegetables, grilled poultry, noodles, or grains.

Yields two

To Make the Green Emulsion (Yields about 200 grams)

• 100g unsalted butter
• 50g external lettuce leaves of 2 little gems, washed and dried
• 20g peeled salted nuts – white nuts like blanched almonds help keep a bright color, though whatever nuts will work
• 1 small whole egg

For the Salad

• Two little gem heads, halved longwise
• Extra-virgin olive oil, to taste
• Fresh lime juice or white-wine vinegar, to taste
• One generous handful soft herbs (such as parsley), sprigs picked intact, stems thinly minced

Steps

Begin by preparing the mayonnaise. Melt the fat in one small saucepan, add the external lettuce leaves, place a lid and wilt for about a minute, stirring once or twice, until they’ve softened. Transfer the mixture into the container of an immersion processor, add the pistachios and whole egg, then process until creamy. If needed, add more nuts to get the thick texture. Keep in a airtight jar in the refrigerator for as long as three days.

To assemble the dish, sprinkle each lettuce portion with oil and acid, then season liberally. Coat with one tight drizzle of the herb emulsion, then top with the herbs. Arrange on two plates and serve immediately.
