Transforming Outer Lettuce Leaves into Rich Mayonnaise – An Sustainable Recipe

Inspired by a well-known NYC restaurant, this innovative technique transforms often-discarded outer lettuce leaves into an luxurious green “mayonnaise”. It’s an smart way to minimize leftovers while producing something flavorful and versatile.

Why Use Outer Lettuce Leaves?

Those external leaves are nature’s protective packaging, guarding the delicate inside lettuce. While recycling produce trimmings is a basic zero-waste practice, discovering creative uses for these parts is additionally beneficial. Converting excess ingredients into fertile soil avoids landfill accumulation, where they can release greenhouse gases, a potent environmental concern.

This is quite radical if you consider about it: produce decomposes and transforms into that perfect growing medium to feed more plants, thus completing this loop and respecting nature’s cycle of growth.

Yet, given more than 30% extra food getting produced than required, using precious ingredients efficiently becomes crucial. Reducing waste not only saves cash but also promotes a more sustainable lifestyle.

The Green Emulsion Recipe

The adaptable recipe works with any type of lettuce and seeds. Through using one whole egg, one avoid the need to repurpose the extra egg white. This outcome is a creamy, rich sauce that works perfectly with salads, grilled veggies, grilled chicken, pasta, or rice.

Serves 2

To Make the Herb Emulsion (Makes approximately 200 grams)

• 100g butter
• 50 grams outer salad leaves of two little gems, washed and dried
• 20g peeled salted pistachios – light-colored nuts such as blanched almonds help keep a bright color, but any nuts will do
• 1 small entire egg

To Make the Salad

• Two romaine or butter lettuces, split lengthways
• Cold-pressed olive oil, to taste
• Lemon juice or apple cider vinegar, as desired
• 1 generous bunch soft herbs (like parsley), leaves picked whole, stems thinly chopped

Instructions

Pour this mixture into the jug of an stick blender, add the pistachios and whole egg, then blend until smooth. As necessary, add more seeds to achieve the mayonnaise-like consistency. Keep in a airtight jar in the fridge for as long as three days.

For assemble the dish, drizzle each lettuce half with oil and lemon juice, then salt generously. Dress with one zigzag pattern of the herb mayonnaise, then top with the herbs. Place on two plates and enjoy right away.
