Wash and pat the chicken drumsticks and fry them in a large saucepan until crispy. Let it stew in its own juice for about 45 minutes at a low temperature.
Peel the potatoes, cut into thin slices and fry in oil.
After 45 minutes add the potato slices to the meat and season with a little white pepper and salt. Stew for 30 minutes at a low temperature.
Heat some oil in a pan and make a roux with the flour. Add the water, lemon juice, vegetable stock, a little salt and the pressed garlic and bring to the boil while stirring constantly. Add the sauce to the saucepan with the chicken and potatoes and simmer for 15 minutes.
