Repurposing External Salad Leaves into Rich Mayonnaise – An Sustainable Recipe
Inspired by a popular NYC eatery, this creative method converts often-discarded external salad greens into an luxurious herbaceous “mayonnaise”. This is a smart approach to reduce leftovers while producing something delicious and flexible.
The Reason Repurpose External Lettuce Leaves?
Those external greens serve as the plant’s protective wrapping, guarding the tender inner leaves. While composting produce scraps is a basic zero-waste practice, finding new uses for them is additionally beneficial. Converting excess ingredients into fertile soil avoids landfill accumulation, where they may release greenhouse gases, a potent climate issue.
It’s rather innovative if you consider about it: food rots and becomes that perfect soil to feed more plants, thus completing this loop and honoring nature’s cycle of life.
However, given over 30% surplus produce being made compared to required, consuming precious resources efficiently becomes essential. Minimizing waste not only conserves money but also supports a more sustainable way of living.
The Green “Mayonnaise” Method
The adaptable formula functions with any variety of lettuce and seeds. By using one entire egg, you eliminate any need to use up the leftover white. The result is an creamy, rich sauce that works beautifully with greens, roasted vegetables, seared poultry, pasta, or rice.
Yields two
For the Green Emulsion (Makes approximately 200g)
- 100 grams unsalted butter
- 50g external lettuce leaves from two romaine or butter lettuce, washed and thoroughly dried
- 20 grams peeled salted nuts – white seeds like blanched almonds help maintain the vivid color, though any nuts can do
- One small entire egg
For the Salad
- Two little gem heads, split longwise
- Cold-pressed olive oil, to taste
- Lemon juice or apple cider vinegar, to taste
- One generous bunch fresh herbs (like dill), sprigs picked intact, stems thinly chopped
Steps
First preparing the emulsion. Heat the butter in one medium saucepan, add the external salad leaves, cover and cook for approximately a minute, stirring a couple times, until they’ve wilted. Pour this mixture into a jug of an immersion blender, add the nuts and whole egg, then process till creamy. As necessary, add extra nuts to get the thick consistency. Store in an airtight container in the fridge for as long as 3 days.
To prepare the salad, drizzle each lettuce portion with oil and acid, then salt generously. Coat with a zigzag pattern of the herb mayonnaise, then scatter with the herbs. Arrange on 2 dishes and serve immediately.
