Inspired by an acclaimed NYC restaurant, this groundbreaking technique converts often-discarded outer salad greens into an smooth herbaceous emulsion. This is a ingenious approach to reduce kitchen waste while creating something delicious and versatile.

Why Use Outer Lettuce Leaves?

These external greens are nature’s protective packaging, guarding the delicate inside lettuce. While recycling vegetable scraps is a fundamental zero-waste practice, discovering creative uses for these parts is even more impactful. Turning excess ingredients into rich soil avoids landfill accumulation, where they can emit methane, a powerful environmental issue.

This is rather radical when you think about it: produce decomposes and becomes the perfect growing medium to feed more plants, thus closing the loop and honoring nature’s process of life.

Yet, given more than thirty percent surplus produce getting made compared to required, using valuable ingredients efficiently becomes crucial. Minimizing waste not only conserves cash but also promotes the more eco-friendly lifestyle.

The Herb-Infused Emulsion Method

The adaptable formula works with any variety of lettuce and seeds. By incorporating a whole egg, one avoid any need to use up the extra egg white. The result is an smooth, rich sauce that works beautifully with greens, roasted vegetables, seared chicken, noodles, or rice.

Yields 2

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

• 100g butter
• 50g external salad greens of 2 romaine or butter lettuce, rinsed and thoroughly dried
• 20 grams shelled roasted pistachios – white seeds such as cashews assist maintain a vivid green, but any seeds can work
• One small whole egg

For the Salad

• Two little gem lettuces, split longwise
• Cold-pressed olive oil, to taste
• Lemon juice or white-wine vinegar, as desired
• 1 small bunch fresh greens (like parsley), leaves left whole, stalks thinly chopped

Instructions

First making the emulsion. Melt the butter in a small pot, add the outer lettuce greens, place a lid and cook for about 60 seconds, stirring once or twice, until they’ve softened. Transfer the contents into a jug of a immersion blender, add the pistachios and whole egg, then process until smooth. As necessary, add extra nuts to achieve the mayonnaise-like texture. Store in an airtight container in the fridge for as long as three days.

To prepare the dish, sprinkle each lettuce portion 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 dishes and enjoy immediately.
