Upcycling External Salad Leaves into Creamy Emulsion – An Zero-Waste Guide

Inspired by a well-known NYC restaurant, the groundbreaking method turns often-discarded outer salad greens into an luxurious herbaceous “mayonnaise”. It’s an smart approach to cut down on leftovers while creating something delicious and adaptable.

Why Repurpose External Lettuce Leaves?

These external greens are nature’s protective packaging, shielding the delicate inner lettuce. Although composting produce trimmings is one fundamental zero-waste practice, finding creative applications for them is even more beneficial. Converting excess ingredients into rich soil avoids dump accumulation, where it can emit greenhouse gases, which is a potent climate concern.

This is rather innovative if you think over it: produce decomposes and becomes the ideal soil to nourish further plants, thereby closing the cycle and honoring nature’s cycle of life.

However, given more than 30% surplus food getting produced than required, using precious ingredients efficiently is essential. Minimizing waste not only saves money but also supports a increasingly sustainable way of living.

The Green “Mayonnaise” Recipe

The adaptable formula works with whatever type of lettuce and nuts. Through using one entire egg, you eliminate any hassle to use up an leftover white. The result is a smooth, rich dressing that works beautifully with greens, grilled vegetables, grilled poultry, pasta, or grains.

Serves two

To Make the Herb “Mayonnaise” (Makes about 200 grams)

• 100g butter
• 50 grams outer salad greens from two romaine or butter lettuce, rinsed and dried
• 20g shelled roasted nuts – white seeds like blanched almonds help maintain the vivid color, though any seeds can work
• 1 small whole egg

To Make the Side

• 2 romaine or butter heads, halved lengthways
• Extra-virgin olive oil, to taste
• Lemon juice or white-wine vinegar, to taste
• One generous handful fresh greens (like dill), sprigs left whole, stems thinly chopped

Instructions

Begin by preparing the emulsion. Heat the fat in a medium pot, add the outer lettuce greens, place a lid and cook for about a minute, mixing once or twice, until they have softened. Pour this mixture into the container of a immersion processor, include the nuts and whole egg, then blend until creamy. As necessary, incorporate extra seeds to get a thick consistency. Store in an airtight container in the refrigerator for as long as three days.

For assemble the salad, sprinkle each lettuce half with olive oil and acid, then season generously. Dress with a tight drizzle of the green mayonnaise, then top with the herbs. Arrange on 2 plates and serve immediately.
