Take the cheese curds out of the fridge so they reach room temperature. Peel the potatoes, cut them into 1 cm thick sticks and soak them in cold water for 30 minutes, then drain and dry them well.
Heat the oil to 160C and fry the potatoes in batches for 5-6 minutes until soft but still pale, then drain on paper towels.
For the gravy, melt the butter in a saucepan over medium heat, stir in the flour and cook for 2 minutes, stirring.
Gradually whisk in both stocks and simmer for 5-8 minutes until thickened, then season with pepper and keep the gravy hot.
Raise the oil to 190C and fry the potatoes again in batches for 2-3 minutes until golden and crisp, then drain and salt them lightly.
Divide the hot fries among 4 bowls and scatter the cheese curds over them.
Pour the very hot gravy over the top and serve at once.
