They say everything has its own time.

And for Chef Petrina Loh, it was only after eight years in her lucrative banking career did she give that all up to pursue her first love of the culinary arts.

The transition from counting coins to wielding kitchen tools came naturally for the 35-year old, seeing how she was born into a family of foodies where her late father serves as her biggest inspiration.

After an extended period of honing her chef skills at the prestigious California Culinary Academy and picking up the tricks of trade in renowned restaurants such as Michelin-starred Spruce, Chef Loh finally settled down in 2013 and had a food baby – a 40-seater restaurant called Morsels.

Here, Chef Loh disregards fleeting food fads, and instead serves up dishes that reflect her culinary ethos – the harmonious fusion of varied ingredients. Think delectable Asian-influenced creations consisting ingredients elevated through the techniques of fermentation, pickling and ageing.

To properly illustrate her thought process of marrying flavours and textures, here is Chef Loh’s Pork Trotter Ragu Rigatoni recipe that is topped with green tomato pickle.
