Pat dry the defrosted hake fillets with kitchen towel to remove excess water from the fish and season both sides with half of the fish spice and black pepper.
In a pan, melt butter and place the fish skin side down, allow to cook on medium heat for 2 minutes, and then flip it over to cook and brown the flesh side for another 3 minutes.
Remove the fillets from the pan and in the same pan add garlic, thyme, paprika, Cajun spice, and the remaining fish spice. Sauté for 1 minute being careful not to burn the garlic, add more butter if needed.
When the spices are fragrant add the cream, bring to a gentle simmer, and add the cooked fish to the pan, allowing it to cook in the sauce for 2-3 minutes on medium heat. Finish the dish off with a squeeze of lemon and season to taste. Serve with buttery mashed potatoes and greens.
