Inspired by a well-known NYC eatery, this creative technique turns often-discarded outer lettuce leaves into an luxurious herbaceous emulsion. This is an ingenious way to minimize leftovers while producing something tasty and flexible.

The Reason Use Outer Lettuce Leaves?

Those outer greens serve as the plant’s protective packaging, guarding the delicate inner leaves. Although recycling vegetable trimmings is a fundamental sustainable practice, finding creative uses for them is even more beneficial. Converting excess ingredients into rich compost prevents landfill accumulation, where it can emit greenhouse gases, a potent environmental issue.

This is rather radical if you think about it: produce decomposes and transforms into the perfect soil to feed more crops, thereby completing the cycle and honoring nature’s cycle of life.

Yet, given over thirty percent surplus produce being produced than required, consuming precious resources efficiently becomes essential. Minimizing waste not only conserves cash but also supports a more eco-friendly way of living.

The Herb-Infused “Mayonnaise” Method

This versatile formula works with whatever variety of lettuce and nuts. Through incorporating one whole egg, you eliminate the need to use up an extra white. The result is a smooth, rich dressing that pairs perfectly with greens, roasted veggies, grilled poultry, pasta, or grains.

Yields 2

For the Herb Emulsion (Makes about 200g)

• 100 grams butter
• 50g outer lettuce leaves from two romaine or butter lettuce, washed and dried
• 20g shelled salted nuts – light-colored nuts such as pine nuts help maintain the vivid green, but any seeds will work
• One small whole egg

To Make the Side

• Two little gem heads, split lengthways
• Extra-virgin olive oil, to taste
• Fresh lime juice or apple cider vinegar, to taste
• One generous handful soft greens (like chervil), sprigs left intact, stalks finely minced

Steps

First preparing the emulsion. Heat the butter in one medium saucepan, add the external lettuce leaves, place a lid and wilt for about 60 seconds, stirring a couple times, till they have softened. Pour this mixture into a container of an immersion blender, add the pistachios and egg, then blend until creamy. As necessary, incorporate extra nuts to get the thick consistency. Keep in a airtight container in the refrigerator for up to 3 days.

For assemble the salad, drizzle each lettuce half with oil and acid, then season liberally. Coat with a tight drizzle of the herb emulsion, then scatter with the herbs. Arrange on two dishes and enjoy right away.
