Poach your leeks to perfection, then pair with pickled pears and nutty miso

I have a great respect for the leek, which is possibly the most demanding vegetable in its need to be freshly cooked before consumption. A warm leek, fresh from the pot, is an ethereal, collapsing sigh of diaphanous veils, whereas cold it can all too easily become a slippery and almost slimy mess of hopelessness.

An umami-packed dish for when you need a flavour hit in a hurry

Here is a simple, practical recipe that I trust will be useful to many who don’t have the time for lengthy kitchen preparations. Boil the spaghetti as usual, drain it, and toss it with a little butter and parmesan. Then, for four, take a spoonful of meat extract and dissolve it in a small saucepan with just a few drops of boiling water. Pour the meat extract over the pasta, stir and serve. You will be pleasantly surprised by the exquisite flavour the pasta acquires – achieved with such a negligible investment of time.

This is a roughly word-for-word translation of an Italian recipe for spaghetti con l’estratto di carne (spaghetti with meat extract). It is another dish from Ada Boni’s Il Talismano della Felicità (The Talisman of Happiness), which was published in English for the first time last month and, according to the food writer and editor Angela Frenda, is “still considered one of the most precise and accurate of all cookbooks”.

A smooth and satisfying soup in nine easy steps

Pumpkin soup, so delicious in theory – sweet, velvety, lightly autumnal – is so often disappointing in reality. Thin in flavour and consistency, thanks to squash’s high water content, it’s likely to make even the most conscientious cook regret not chucking those Halloween offcuts on the compost heap when they had the chance. This, I hope it goes without saying, is not that sort of pumpkin soup.

These highly crunchable cheesy bread balls are a great way to use up odds and ends

Sadly, I’m never going to be able to recreate the cheese and bread balls I made a few weeks ago, because, of the four cheeses used, I recognised only two of them: a bit of gorgonzola and a slice of precious Montgomery cheddar, bought from Da Corrado, a stall on Testaccio market. The other two lumps of cheese, both wrapped in white waxed paper and both quite dry, were, I think, a piece of grana padano and the end of the pecorino we brought back from Umbria. But I can’t be sure, because I didn’t really examine them. Even if I had, it would have been hard to guess; the description “heels of cheese” is appropriate here. What I do know, however, is that the combination of those four grated cheeses with two eggs and enough breadcrumbs to turn the mix into a soft, malleable dough made for fantastic deep-fried balls.

The inspiration for using up the uncertain contents of the cheese box was pallotte cacio e ova, which translates as “little cheese and egg balls”, a typical and much-loved thing in both Molise and Abruzzo, which were, in fact, one region until 1964. Pallotte are resourceful, and were surely invented as a way of using up scraps of cheese (almost certainly local pecorino) and bread. Whatever combination of cheese you use, though, the important thing is to add enough soft white breadcrumbs – anything from 80g to 120g – to turn the mixture into a soft dough that you can then mould into balls, but not so compactly that the tenderness is lost. Like meatballs, cheese balls benefit from a rest in the fridge, so they can firm up before frying. The rest in the fridge also ensures that they are cold, which is important, because the thermal shock of the cold surface meeting the hot oil helps create a crisp shell.

A creative way to use up the bits you already have around, all while getting in a healthy mixture of vegetables and whole grains

This hearty dish is inspired by the diets of the Blue Zones, or those regions of the world where people live the longest, including Sardinia, where minestrone is a staple. Dan Buettner, who studied these communities, found that their diets are generally rich in beans, whole grains and seasonal vegetables. I’ve generalised ingredients into groups such as alliums, rather than simply suggesting the standard onion base, to inspire you to use up whatever you have in the house and what’s in season; I’d of course also encourage further diversification with the addition of other vegetables and subtle spices.
