Inspired by something his mum used to make, Mr Moroni cooked a batch of caramel-coated nuts to hand out at a university guild day, with partner Marie Mapp bagging the delicious goods.
They were so positively received that the duo are now celebrating the 21st anniversary of their Herne Hill-based business Morish Nuts.
Mr Moroni had to give up his studies to concentrate on the burgeoning business, which started with a stall at Fremantle Markets that still operates today.
He said his secret to success was providing free samples, something other businesses at the time did not do.
�Inevitably once you have tasted it, seven out of eight times you�ll want to buy it,� he said.
A major coup came when Virgin Australia included Morish Nuts on its in-flight menu more than a decade ago.
Feedback from passengers also encouraged them to create a savoury version.
The original caramel-coated nuts remain a staple and though Mr Moroni said they had experienced �a few major flops�, Morish Nuts now offered more than 20 different flavours.
�We�re constantly innovating, it is probably what keeps us on our toes,� he said.
�The quality of product coupled with the way it is designed and delivered is what sets us apart.
�We�re not selling as a snack; it�s designed as a special treat and gift.�
Morish Nuts factory and retail outlet opened in Herne Hill in 2013, which Mr Moroni said was a great way to connect with customers.
�Sometimes you can hear a group from the factory and you can go out and interact,� he said. �It�s a good feeling because they can see where it comes from, see how it�s made, smell it being made and taste it; it�s a lovely way to do business.�
Being a part of the Swan Valley region was ideal for their business as well.
�It�s like wine tasting � you can buy wine at the bottle shop but it always tastes better when you go to the cellar door and you can talk to the winemakers,� he said.
Though success came unexpectedly, Mr Moroni said it had been an enjoyable journey and he and Ms Mapp made a good team.
�I was happy to make the nuts but someone had to tie the ribbons on the bags,� he said.
