One of the most remarkable, most memorable meals I had during my time in northern Italy was agnolotti, stuffed pasta parcels typical in the Piedmont region, an area to the west of where I was staying in Calestano, in Emilia-Romagna. Pasta stuffed with potato – double carbohydrate heaven – was a popular choice in the locality, sometimes simply seasoned with plenty of Parmigiano Reggiano, sometimes with added truffle-y excitement as well. And so it was to become a popular choice with me as well. Handmade pasta, truffle and cheese infused stuffing, a breathtakingly rich cream sauce with lashings of added butter and fresh, local black truffle. Complete and utter bliss . . . Adriana, a native of the area with many decades of culinary experience, taught me what she knew about these little parcels of joy.
The first step in executing this wonderful dish is making your preparato – an essential ingredient in the local cuisine. Made with varying proportions of finely grated Parmigiano Reggiano and black truffle, this mixture is stored in the freezer, extending the truffle season right through the year. Truffle is a notoriously difficult ingredient to store, its distinctive aroma lost as soon as any processing is applied to it. But the fats in Parmigiano Reggiano cling to the truffle's volatile aroma compounds, helping capture that ephemeral, highly prized flavour. This mixture perfumes the potato filling and the luscious cream sauce, as well as being liberally sprinkled on top, bringing the flavour of last year's truffles to my grateful lips.
