Tackling Food Waste: Cooking with By-Products

By Maurice Mc Geehan posted 07-06-2018 15:27

  
People always try to make the most of what they buy so food shouldn’t be any different, especially ingredients coming into your kitchen everyday.

Making use of the entire produce is not as difficult as it may seem; us, chefs, do it on a daily basis to a certain extent, it is in our nature to save the peelings for stock, or gathering heals and crusts of bread crumbs for bread and butter pudding.

Nowadays, more and more chefs are coming up with ingenious ways to make the most of food byproducts using modern techniques but for me, the old approaches are the best; the way people did it hundreds of years ago, preserving their food with methods such as drying or dehydrating, pickling, fermenting, curing and smoking, all great ways to keep food in the pantry for longer periods of time but also because each method develops its own unique flavour, and are techniques we use every week on what is left after the core of a product is used.

In a commercial and modern kitchen environment, this is also a great way to keep the team engaged and motivated, while keeping the old cooking techniques alive. When I look at trimmings, leaves and byproducts from fresh produce, I see many another ingredients to use in the kitchen, and I get as excited about that as I do about the core of the product.

Imagination and the willingness to give something new a shot are great tools when you look at  turnip leaves and stalks, salmon skin and belly, pineapple core and many other peelings in waste tubs around the kitchen, in each chefs sections, after an hour of mise en place.

To come up with a dish that's star components are bits of food that would normally go in the bin, needs some imagination and it is a fantastic challenge for chefs of all levels, in any kitchen. For instance, we’ve done a pop up dinner in the office which coincided with Earth Day, so we used some of our Airbnb experience hosts’ products but the core of the menu was developed around by-products.

We’ve designed a menu were 65% of the dishes was made of components that would normally go into the bin; we served plated starters, family style main courses and plated desserts, all served on our normal lunch plates and bowls to show our guests that it is something anyone can do at home - and most wouldn’t even think that the dishes were primarily made from by-products.

The menu was a reflection of what we do at Airbnb on a daily basis like making cider vinegar from apple skins and cores, extracting the pectin and sugar from the skins to get something like a fruity sweet honey; making teas and pineapple molasses from the skins and core of pineapples, after the flesh has been used on our breakfast - the pineapple molasses is very similar to the best know pomegranate version and it would be extremely hard to tell the difference in a blind taste test.

When we make our own cheese we use the whey as bases for soups and sauces, sorbets and even into delicious drinks in our in-house drinks programme; when we make yogurt we use the acid whey for pickling.

The pineapple skins, salmon skin and belly all mentioned above made one of my starters, the Turnip leaf dolmas - crispy salmon skin, salmon belly bonito, Oriel Teelings smoked salt, Mungo Murphy's sea lettuce, fermented pear, pineapple skin molasses.

As part of the Earth day theme I used Oriel’s salt smoked with Teelings old oak barrels - used to age the whiskey - to season the crispy salmon skin in the dolmas, a great story of circular living and zero waste to add to the menu.

We also used sea lettuce from Mango Murphy, who is an Airbnb experience host; the dish balanced out really well with the saltiness from the salmon skin, sweet and acidic pineapple molasses, fermented overripe pear and the smokey salty salmon belly bonito style.

In the old days nothing went to waste and I can see a resurgence of this in recent years; my time in Brazil taught me to make the most of what I had available to me as I couldn’t get many ingredients that we, European chefs, take for granted.

There, I’ve started to make my own bacon, curing and fermenting my ingredients, and I can see the same happening here now, with many chefs committed to using everything that comes into their kitchens, what is not only good ethos but something really interesting and exciting to do while pushing to achieve the 75% GP and minimising food waste, not to mention the feeling of satisfaction that we get doing something that might seem so small that makes such a huge difference to the world.
