REDUCING FOOD WASTE IS GOOD FOR THE PLANET AND YOUR POCKET
REDUCING FOOD WASTE IS GOOD FOR THE PLANET AND YOUR POCKET
By Holly Taylor, chef and co-founder of Kindling Restaurant in Brighton
Unfortunately, in many households, the best fed occupant is the bin. More than 30% of all food produced globally is thrown away. The UK is by far the worst offender in Europe: we chuck 9.5 million tonnes of food each year. This isn’t just a waste of time, money and resources – it is an enormous problem because as food degrades in landfill sites it releases methane gas which contributes to global warming.
At Kindling restaurant in Brighton, we design our whole menu around using amazing local produce and minimising food waste. Here we a few ways you can help tackle the food waste issue at home, plus save money.
Know what you’ve got
The peel from onions, garlic and shallots can be used to make an amazingly fragrant oil for dressing and cooking with. Simply save all your trimmings in a bag in the freezer until you have enough to fill a large saucepan. To make the oil, cover all the peelings with a neutral tasting oil such as rapeseed oil and heat over a very low heat for 2-3 hours. Allow to cool, then strain and decant into bottles. This oil is lovely for cooking with or as a base for a salad dressing, or a dip for bread.
A large proportion of green vegetables is often thrown away simply because we don’t think its edible or don’t know what to do with it. The green part of a leek still tastes amazing, it simply needs to be well washed and cooked for a bit longer than the paler part. The outer leaves of cauliflower are gorgeous roasted in the oven for 5 minutes at 220C with a little oil and salt, but they’re equally good shredded in a stir fry or added into a cauliflower cheese. Broccoli stalk is delicious sliced and pickled in a salad.
In the restaurant all our green trim is saved, thinly sliced, and then turned in a beautifully vivid green soup which we offer to our evening diners as an amuse bouche. The finely chopped greens are sauteed in butter, then cooked out in milk before being blended into a silky-smooth soup that’s chilled over ice. Everything from the outer leaves of cabbage to the trim from broccoli can feature in the soup. It simply depends what’s on the menu at the time.
Be smart with your freezer
Some of the most commonly thrown away food items are wrinkled chillis, pieces of mouldy root ginger and citrus fruits that have been zested and become dried out. If you keep all these things in the freezer, you can grate them straight from frozen. This means you can easily portion half a chilli, the zest of half a lime or 1 tablespoon of ginger without the rest going to waste. Once you have what you need simply return the item to the freezer ready to use again next time.
Be crafty with preserving and fermenting
If you end up with too much of something there are a lot of different ways you can preserve it for use later in the year.
Gluts of fruit and vegetables can be turned into jams and chutneys or pickled. These make excellent presents or additions to a Christmas hamper.
Cabbages and root vegetables like carrots and beetroot can be turned into kraut. Thinly slice or grate the vegetables, carefully weigh how much you have and sprinkle in 3% table salt by weight. Set the veg aside for an hour then massage it with the salt until it creates enough liquid to fully cover itself when put in a jar. Pack the vegetables and liquid into a Kilner jar ensuring they are fully submerged, then seal and leave in a cool dark place to ferment for anything from a week to six weeks. It’s a good idea to open the jar once a week and have a taste to see how the flavour is developing. Once it’s reached a taste that you’re happy with, transfer it to the fridge.
Softer fruits and vegetables can be fermented in a brine (salt dissolved in water). Sweeter fruits such as apples and plums should be fermented in a jar in a 5% salt solution. Less sweet fruits like rhubarb, and most vegetables can be fermented in a 3% brine. Simply place the prepared food in the jar, fully submerge in brine and seal the lid. Leave at room temperature for a week to 10 days then transfer to the fridge. As fruits and vegetables ferment, acids develop and gas is produced. For this reason, it’s a good idea to ‘burp’ your jars every few days while they are actively fermenting to avoid explosions!
Once fermented, fruits and vegetables will keep for months in the fridge provided they stay in the fermentation liquid. On a dark winter’s day, it’s nice to have a splash of colour from some fermented rhubarb or the zing of a preserved plum to remind you summer is not far away.
Some items of food waste can make excellent additions to your garden or allotment. Crushed eggshells make an excellent slug and snail deterrent around young plants, or they can be dug into the soil to add vital nutrients for seedlings. Coffee grounds can be added to soil to create a nitrogen rich environment loved by plants such as onions and salad leaves. And of course, anything you really can’t find an edible use for can be used to start a compost heap. Unlike in a landfill site, food decomposing in a compost heap doesn’t produce greenhouse gases so it’s a much better choice than putting food in the bin. At Kindling any veg trim we can’t use is collected and sent back to our local growers to use as compost, creating a closed loop where nothing is wasted.
Let us eat cake
Over ripe fruit and vegetables that have gone a bit soft like carrots and courgettes are perfect for baking. Many other fruits and vegetables can also be pureed or grated and added into sweet loaves, cakes, muffins and cookies. Think banana bread, courgette and lime loaf cake, apple sauce muffins and carrot cake cookies!
Household food waste accounts for 60% of all food waste, so even small changes in the amount each family throws away can make a big difference. Being careful with how much you buy, keeping an eye on use by dates, and getting savvy with the freezer are all great ways to start minimising how much food ends up in the bin. And with a bit of creativity and know-how you can start using more of what you buy and getting value for money too.
