Step 1

Place potato in a pan and cover with cold water. Bring to the boil over medium-high heat and cook for 20-25 minutes or until tender. Drain, then return potato to pan over low heat. Cook, shaking the pan, for 1-2 minutes to remove excess moisture.

Step 2

Pass potato through a potato ricer into a bowl and season. Add eggs, nutmeg and flour and bring mixture together with your hands to form a soft dough - be careful not to overwork it. Divide mixture into 6 portions and roll each into a thin log, then cut into 2cm pieces.

Step 3

In batches, cook gnocchi in boiling salted water for 1 minute or until they float to the surface. Remove with a slotted spoon and plunge into a bowl of iced water. Drain and set aside.

Step 4

Heat 1 tablespoon oil in a pan over medium-high heat. Add the pancetta and cook, stirring occasionally, for 2-3 minutes until pancetta starts to crisp. Remove and whiz in a small food processor until fine, then return to the pan. Reduce heat to medium, then add garlic and cream, and cook, stirring occasionally, for 6-8 minutes until sauce has reduced by about one-third. Season well and keep warm.

Step 5

Meanwhile, melt butter with remaining 1 tablespoon oil in a frypan over medium-high heat. Cook the gnocchi, in batches if necessary, for 2-3 minutes, turning, until golden. Gently toss the gnocchi with the peas and cream mixture until combined.

Step 6

Season, then garnish with parmesan, if using, and parsley. Serve immediately.
