Food waste statistics boggle the mind. We may all have a statistic that leaves us incredulous. For me, it’s bread. In the UK, the amount of bread wasted totals 1 million loaves, or 24 million slices, every day, according to the Office of National Statistics. Food waste in the US is put at 30-40 per cent of the total food supply, according to the US Department of Agriculture. The numbers are overwhelming.

There’s a lot that needs to be done on a large scale. Much of it should be the responsibility of the big food manufacturers and retailers. At the same time, there’s plenty we can be doing at home, by ourselves.

The first suggestion is practical: Buy less food at once. The second is more creative: Use up - and make full use of - what we already have. Now, using up and making full use of are slightly different things, but both can be a huge source of inventiveness and deliciousness. They’re where the fun, the innovation and the surprises come in.

“Using up” simply means using up those last bits. If the last slice or two of bread is looking a bit sorry for itself, don’t chuck it. Blitz it instead. Make bread crumbs for your next round of vegetable schnitzels. Or freeze the bread crumbs for another time. Or use the day-old bread as a springboard for a whole new dish: panzanella, ribollita, romesco - a salad, a soup and a sauce whose very reason is the stale bread that inspired them.

“Making full use of” offers even more room for exploration. It means looking at the things we think we’ve used to their full potential, and seeing if we can’t eke out one more use. These are the vanilla pods added to a jar of sugar once the seeds are scraped out, or the herbs wilting in the fridge that we blend with avocado and olive oil, for a glossy, green dressing, for example.

If you have too much of something, turn it into something else. Labneh, for example, is simply yogurt hung over a sink for a day or so, in a clean tea towel or muslin, for the whey to drain away. The result can be rolled into balls, covered with olive oil and kept in the fridge for weeks. Or it can be used to make lemon possets: a classic British pudding made with just three ingredients - cream, lemon and sugar.

And so on to the one ingredient I can never have too much of in my kitchen: lemons. I am pretty good at using the whole lemon. I finely grate the zest, I greedily squeeze the juice, I meticulously separate the segments. I drink it, I eat it, I live it, I love it.

Here, I burn and grind the peel for a burnt lemon powder that will be a source of pleasure and delight on all the salads, puddings or grilled foods it is sprinkled over.

Making burnt lemon powder isn’t going to reverse the tide of global food waste, I know. But it is a useful example of how much we can get out of what we have, of how many creative juices - citrus or otherwise - can flow if we get into the habit of checking ourselves before throwing things away.

As the saying doesn’t quite go: “When life gives you lemons, make lemonade (and limoncello and burnt lemon powder and, of course, the most citrusy of lemon possets).”

Lemon-labneh possets with meringue and burnt lemon powder

Makes 8 possets

“Simple ingredients made super special” could not be more true of these lemon possets, which are well worth the effort for their perfect combination of creamy, tart, sweet and crispy. A posset is a quintessential British dessert and has a similar consistency to that of a custard or pudding, but acid (lemon juice in this case) is used to set the base as opposed to egg yolks or cornstarch. There are a number of shortcuts you could take, including using store-bought labneh or replacing it with an equal amount of thick-set créme fraîche. You can also use store-bought meringues, crushing them lightly to sprinkle on top. The burnt lemon powder is an added bonus and a great way to use up lemon peel that you may have otherwise discarded. You can use this powder in a number of inventive ways, including sprinkling it over hummus or some roasted vegetables for added depth. If you are making your own labneh, be sure to start the day before.

Ingredients

For the labneh (optional):
450g Greek yogurt
½ tsp sea salt
For the posset:
1 tbsp lemon zest (from 1 to 2 lemons)
200g lemon juice (from about 4 to 5 lemons)
250g sugar
650g double cream
200g labneh (homemade or store-bought)
For the meringue:
115g sugar
2 egg whites (65g), from 2 large eggs
1/8 tsp cream of tartar
For the burnt lemon powder:
2 unwaxed (or well-scrubbed) lemons

Method

1. Make the labneh: Add yogurt and salt to a bowl and mix well to combine. Line a medium sieve with a piece of cheesecloth or a clean tea towel with plenty of overhang. Add yogurt, and pull the overhang up and over the yogurt to encase it. Set the sieve over a bowl and place a weight on top. (A couple of tins will do.) Refrigerate for 24 to 48 hours. When ready, discard the liquid collected and store the labneh in a sealed container in the refrigerator for up to 3 days. (You should have about 250g of labneh.) If using store-bought labneh, skip this step.

2. Measure out a scant 200g of labneh for the possets, and reserve the rest for breakfast or to spread onto toast.

3. Prepare the possets: Combine lemon zest, juice and sugar in a medium saucepan and bring to a boil over medium-high heat, stirring occasionally to dissolve sugar. Set aside once the sugar has dissolved. In a separate medium saucepan, heat double cream over medium until it just gently starts to bubble, 7 to 10 minutes. Off the heat, pour all the cream into the lemon mixture and whisk until combined, then whisk in labneh until smooth. Strain mixture through a fine-mesh sieve set over a jug with a spout. Divide mixture across 8 glasses. Refrigerate for at least 4 hours, or overnight if you’re getting ahead.

4. Prepare the meringue: Heat oven to 180 degrees Celsius. Spread sugar onto a baking tray and heat for 10 minutes, until very hot but not melted at all. A couple of minutes before it’s ready, add egg whites and cream of tartar to a stand mixer fitted with the whisk attachment (or alternatively, use an electric hand mixer), and beat on medium until frothy, about 1 minute. Remove sugar from oven and turn down the temperature to 120 degrees Celsius. Turn mixer speed to low and slowly stream in the warm sugar until it’s all incorporated. Turn the speed back up to high, and beat until glossy and stiff peaks form, another 5 to 6 minutes. Line a large (roughly 40-by-30-cm) baking tray with parchment paper and use a spatula to thinly spread the mixture onto the lined tray, so it’s about 35 by 25 cm. Bake for 80 to 90 minutes, until completely dried out. Set aside to cool, about 30 minutes, then roughly break apart into random shards.

5. Prepare the burnt lemon powder: Turn oven up to 230 degrees Celsius. Use a small, sharp knife to cut the peel off the lemons in long strips. (Don’t worry if you get some of the pith.) You want about 30g in total. Transfer strips to a small, parchment-lined baking tray. Bake for 12 to 15 minutes, until completely dry and almost burned. They’ll shrivel significantly. Transfer to a pestle and mortar to finely grind, then pass through a sieve, to catch any large pieces. (Discard these.) You should be left with about 1½ teaspoons.

6. Segment the lemons: Using the small, sharp knife, trim off any excess peel, then cut between the membranes to release the segments. Roughly chop each segment into 2 to 3 pieces. (Use them all if you like things a little sharp, or keep any extra in the fridge for a vinaigrette or salsa verde.)

7. To serve, top possets with lemon segments, a sprinkling of burnt lemon powder and a few meringue shards, serving any extra meringue to dip alongside. - This article originally appeared in The New York Times
