His secret to a good pie would remain that - except to say it was all about the process of making pastry, rather than the ingredients, Lam said.
Lam is a well-known name in pie-making circles, having won more than 50 pie awards, including the supreme pie award four times - now five - since first entering in 2003.
Along with the supreme award, for which he received a trophy and $7500 cash, Lam won silver for his steak and cheese and gold for his bacon and egg, and was also highly commended for his gourmet fruit pie.
The awards were presented at "The Pies of the Round Table", a medieval-themed gala dinner at the SkyCity Convention Centre in central Auckland.
Top chef and celebrity judge Mark Southon, of TV3's The Café, was stunned by Kiwis' passion for pies. The Brit, who is also executive chef at O'Connell St Bistro in Auckland, said he was impressed by the innovative fillings.
"We saw some interesting skills and flavours, such as alpaca and kimchi; braised lamb shank and butter chicken. There were nostalgic and Kiwi heritage pies like creamed paua, smoked fish and the addition of kumara to some pies.
"One of my personal favourites was a take on the British pork pie from the South Island, and a smoked fish pie that was in the style of a pithivier [a round pie made of two discs of puff pastry with filling between]."
Chief judge Tim Aspinall has been judging pies for 13 years and said the competition had become tougher to judge every year.
"This year's entries were a mix of traditional braised meats, exotic combinations and ethnic fusions.
"What I look for in a winning pie: does it say 'eat me?' Does it have the wow factor and invite me to go further? Is the pastry evenly cooked to a golden brown? Does the aroma and flavour want me to pick it up and eat more? "Patrick's winning bacon and egg pie ticked all these boxes."
