4xFour is organised by the same team that runs casual outdoor festival Savour. Limited seats are still available to try the cuisine from other acclaimed chefs cooking for the 4xFour event at The White Rabbit at 39C Harding Road.
The other three chefs are Claude Bosi from two-Michelin-starred Hibiscus in London, Davide Scabin from two-Michelin-starred Combal.Zero in Italy and Ollie Dabbous from Dabbous in London.
Morales says that having a halal option will not take away from the dining experience at Noor.
For example, his dish called Perfecto-Imperfecto de Maiz - which is sphere of corn mousse filled with crab and smoked herring caviar, dusted with smoked bacon powder - will simply do without the bacon element for the halal menu. It was served at 4xFour.
He says: "No pork, no wine, no problem. The dishes can remain similar, it is up to our creativity."
Other dishes featured at 4xFour included slow-roasted pigeon with handmade polenta gnocchi served in pigeon broth; and turnip pudding with turmeric, lemon and crisp sea bream.
Some of his favourite ingredients to cook with include argan oil, rose water, saffron, turmeric, cinnamon and cumin.
The Christian chef had his sights set on taking halal cuisine to a new level after the closure of his four-year-old restaurant Ferrero in 2013 due to financial issues. In 2010, Ferrero - which served modernist Spanish cuisine - was awarded its first Michelin star. He is also the consulting chef for Al Trapo in Madrid, Spain, which serves "informal haute cuisine".
While his past experience working with the likes of elBulli chef Ferran Adria has shaped his style of "creative cuisine", Morales' decision to go halal was largely influenced by his hometown of Cordoba. Back in the 10th century, it was a predominantly Muslim society.
"My cuisine will be influenced, and influential to the culture in Cordoba. I want to recreate what it was like then," says Morales, who emphasises the need to pay attention to the melting pot of cultures in the region - from Arabs to Christians and Greeks.
The soft-spoken chef grew up in a family of cooks and picked up cooking from his father. His parents still run their 30-year-old deli-restaurant Asador de Nati, which serves traditional fare such as beef oxtail and roast chicken with vegetables. Two of his three sisters, aged 33 to 39, work at the restaurant.
His 29-year-old wife handles the administration and finances for Noor. They do not have children.
Lamenting that there are not enough halal restaurants in Cordoba, Morales hopes that more business owners will follow in his footsteps.
He says: "To develop the business and culture of Cordoba, we need more halal restaurants."
