Upcycling Outer Lettuce Greens into Creamy Mayonnaise – A Sustainable Recipe
Inspired by a popular New York eatery, the innovative method transforms often-discarded outer lettuce greens into an luxurious herbaceous “mayonnaise”. This is an brilliant approach to cut down on kitchen waste while producing a condiment delicious and versatile.
The Reason Use Outer Salad Leaves?
These outer greens serve as nature’s protective wrapping, shielding the delicate inside leaves. While composting vegetable trimmings is one basic zero-waste practice, finding creative uses for these parts is even more beneficial. Converting surplus food into rich soil prevents landfill buildup, where they can emit methane, which is a potent climate concern.
This is rather innovative when you consider over it: food rots and becomes that ideal soil to feed further crops, thereby completing this cycle and respecting nature’s cycle of growth.
However, with more than 30% surplus produce being produced than needed, consuming valuable resources efficiently is essential. Minimizing leftovers not only saves money but also promotes a more eco-friendly way of living.
The Green “Mayonnaise” Recipe
This versatile formula works with whatever type of lettuce and seeds. Through incorporating one entire egg, you eliminate any need to repurpose an leftover white. This outcome is a smooth, nutty sauce that works perfectly with salads, roasted veggies, seared chicken, pasta, or grains.
Serves 2
To Make the Green Emulsion (Yields approximately 200 grams)
- 100g butter
- 50g external salad greens from two romaine or butter lettuce, washed and dried
- 20 grams peeled salted pistachios – light-colored nuts such as pine nuts help keep a vivid green, but whatever nuts will do
- One small entire egg
To Make the Side
- 2 little gem lettuces, halved longwise
- Cold-pressed olive oil, as needed
- Fresh lime juice or white-wine vinegar, as desired
- One small handful fresh greens (like chives), leaves left intact, stalks finely chopped
Instructions
Begin by preparing the mayonnaise. Melt the fat in a medium saucepan, toss in the external salad leaves, place a lid and cook for about 60 seconds, mixing a couple times, until they have softened. Transfer the contents into the container of a stick processor, add the pistachios and whole egg, then process until creamy. If needed, add extra seeds to get the thick texture. Store in an airtight jar in the refrigerator for as long as three days.
For prepare the salad, drizzle each lettuce half with oil and lemon juice, then salt liberally. Dress with a tight drizzle of the green mayonnaise, then top with the herbs. Place on two dishes and enjoy right away.
