Known as grana (grains) in the locality due to the way Parmigiano Reggiano is produced, the cheese makes it into almost everything. A typical family will grate and sprinkle their way through about a kilogram a week and seeing an industrial Parmesan grinder, pride of place on the kitchen counter, is the norm. The habit is formed early, with children given a piece of cheese to occupy them as their parents shop, and it stays for life.

Typical of these livestock-farming regions of northern Italy, meat, butter and cream are used in abundance, with Parmesan seasoning and deepening those meaty, creamy flavours. Parmigiano Reggiano is served plain, in great crags on a plate, or perhaps with a drop of rich, sweet, long-aged balsamic vinegar – also produced nearby, but less well-known than their counterparts in Modena.

A mix of Parmesan and grated black truffle, the latter a speciality of the nearby town of Fragno, is always on hand in the freezer. Helping them extend the truffle season right through the year, it is known simply as preparato (mix) and finds its way into countless dishes. Parmigiano Reggiano is shaved into salads, worked into stuffings and kneaded into gnocchi. It flavours meat, fish, grains and vegetables, even fruits – perhaps slice of apple or pear, or dried figs or plums – all a match.

This is a cheese that the local people feel strongly bonded to, both by nature and nurture – none more so than the first woman I was lucky enough to visit, Adriana Salsi. Neat and precise, with twinkling eyes and short, tidy hair that frames her happy face, Adriana has spent all of her seventy-six years living in this mountain area.

Her kitchen fills me with both awe and inspiration, coming complete with internal wood-fired oven (as well as the traditional gas burners and stove), plenty of beautifully polished copper and a fifty-year-old wooden chopping board, made by her late husband, deeply grooved from a lifetime of use. Hard-working, with exceptional attention to detail, she tackles task after task with the mantra: 'I’d better do it this year, in case I can't do it next year.' With only three years of school, her kitchen is una cucina instinctiva, where ingredients are measured by eye and seasoned to taste. She tells me: 'Life is more about practice than grammar.'

Received into her home and family with extraordinary grace and hospitality, she took me through but a few of Parmigiano Reggiano’s many applications. Speciality after speciality was whipped up, laid out and pressed to my lips. There was Melanzane alla Parmigiana – thin, grilled slices of aubergine with mozzarella and tomato, all layered with generous sprinkles of a rich, fruity, twenty-four month cheese. Creamy, silky polenta came enriched with a truly indecent amount of butter and endless, snowy grinds.

Her delicate pasta parcels, Agnolotti, came stuffed with soft potato, black truffle and yet more umami Parmesan – finished with a creamy sauce of incomparable richness and plenty more freshly grated truffle. But for added drama, the dish of the day went to her Bomba di riso, an enormous baked arborio rice creation, stuffed with a rich, meaty sauce (or a variety of well-seasoned vegetables) and unveiled with great ceremony from its ancient copper pot to rapturous applause. From me. It was one of the great memorable meals of my life. Her dishes and the methods she so generously shared – not to mention her overwhelming kindness – will stay with me forever.

Silvana Ghillani has a face that sparkles with smiles and enthusiasm and a joyful shock of curly hair that belies her seventy years. Her walls and cupboards display her collection of antique plates and ceramics, and her favourite picture – a 17th-century print of history's only female Pope – hangs in the hall. She told me: 'I have done courses in everything! Lacemaking, knitting, patisserie, dancing – I needed the learning to occupy my mind and my time.'

From the window of her kitchen you can see the tiny house her late husband was born in, across a garden filled with all manner of delicious edibles, just waiting to be harvested. She collects her drinking water from her own forest well and bakes all her own bread. Not only to feed herself, but for the legions of loved ones and acquaintances that surround her. She told me: 'I have two Thermomixes – I couldn't live without them!' When her husband was alive, she said, gardening was one of his great passions and she would process the results: 'One year that meant over 1500 portions of minestrone – we had to buy three extra freezers!' Her three most important kitchen appliances – a Thermomix, Parmesan grater and espresso machine – tell you a lot about Silvana and her cooking.

She told me: 'I have been very, very lucky. I came from a very poor family, but I have always had everything. I had a happy childhood, I was extremely happy with my husband, for all our fifty-three years together. My life has been a beautiful one, I've had the best life I could have hoped for. I've been very, very lucky. Once I start saying it, I can't stop!'

The feast I experienced at Silvana's house began with espressos and caramelised walnut cake, made with nuts from her own trees, just in case we got peckish before the multi-course extravaganza began.

Central to the meal was her Roast belly of veal, stuffed with her own homemade breadcrumbs, dried porcini mushrooms and vast quantities of Parmigiano Reggiano, as well as plenty of lovely aromatics. Incredibly tender, basted in white wine as it slow-roasts, the final, elegant slices are drizzled with the rich cooking juices for even more moisture and flavour.

Another highlight was the Parmigiano Reggiano gnocchi – two mouth-watering kinds. Watching Silvana knead, roll out and cut her gnocchi was hypnotic, rhythmic and beautiful. The light, yolk-tinted dumplings had a sheen of flavourful cheese kneaded into the dough, and after boiling remained delicate with a little welcome chew. Sauced with the choice of an impossibly fragrant tomato-basil sauce, made of course with vegetables and herbs from her sun-soaked garden, or lashings of butter with fresh sage – this all under a downy blanket of Parmigiano Reggiano. What could I do but blissfully accept both? And to finish, yet more of that caramelised walnut cake – 'prize-winning' Silvana tells me with a big smile. Did I mention the homemade walnut liqueur?

I spent much of this trip gently dabbing a tear from my eye, not least when Adriana shared her prized, secret recipe book with me. It was a deeply emotional experience to be welcomed into these women’s homes and hear what they had to say about food, cooking and happiness. Adriana’s sister, Mina, looked on proudly as her sibling explained exactly how I should make her agnolotti, telling me: 'Housewives are not usually the centre of attention here, they don't really get the recognition. It's nice to see their work being appreciated…'
