Salt hake fritters with orange alioli

Method

1. To make the salt hake, put half the 250g salt in a non-reactive dish (glass or ceramic are good choices) along with half the thyme and half the chopped garlic. Put the hake on top, then completely cover with the remaining salt, thyme and garlic.
2. Cover the dish with cling film, then chill for 24 hours, turning the fish and re-covering with the salt mix every 8 hours. After 24 hours, remove the fish from the salt and soak in a bowl of cold water for 15 minutes. Drain, add fresh water, leave the fish for 15 minutes more before draining and rinsing again, then pat it dry.
3. To make the fritters, heat the oven to 200°C/180°C fan/gas 6. Sprinkle the 100g rock salt in a baking tray and put the potato on top (the salt will help to draw moisture out of the potato). Cook for 1¼ hours or until the potato is soft. When it’s cooled a bit, peel, then break up the flesh.
4. While the potato is cooking, make the orange alioli: put the 100ml orange juice in a small saucepan, then bubble until sticky and reduced by two thirds. Whisk it into the alioli, then cover and chill until needed.
5. Put the salt hake in a pan and cover with the milk. Add the garlic, bay and rosemary, bring to the boil, then turn off the heat and leave the fish to cook in the residual heat from the milk. Set aside to cool.
6. Bring the butter and 150ml cold water to the boil in a large saucepan, then stir in the flour. Beat well with a wooden spoon until a dough forms and comes away from the sides of the pan. Remove from the heat and cool for 5 minutes.
7. Slowly add the eggs, beating in well to make a smooth, shiny choux paste.
8. Remove the cooled hake from the milk, then flake into large chunks into a bowl. Add the potato, hake, 1 tbsp orange juice and some pepper (it won’t need salt) to the choux paste. Mix well, then cover and chill for 2 hours (see Ben’s tips, below).
9. Shape into small balls or croquettes, then chill for at least 20 minutes to firm up (see Ben’s tips).
10. Heat the vegetable oil to 180°C in a deep fat fryer (or half-fill a large pan with the oil, then heat to 180°C on a digital probe thermometer).
11. Fry the fritters for around 3-4 minutes until golden – you’ll need to do this in batches so as not to cool the oil down too much.
12. Remove with a slotted spoon, then drain well on kitchen paper. Serve with the alioli.
