On the side
- 800 gPotato, cut into chips
- 5 tbspOlive oil, for frying
Method
- Halve the kidneys lengthways and cut out the white core and fat with a sharp knife. Cut them into bite-sized pieces.
- Put the pieces in a bowl of cold water with the vinegar and leave them to soak for 30 minutes to tone down their strong flavour.
- Meanwhile, peel the potatoes and cut them into chips. Rinse in cold water and dry thoroughly with a clean tea towel.
- Finely chop the onion and garlic, and chop the parsley.
- Heat the oil in a casserole and gently fry the onion and garlic over a low heat for 10 minutes, until soft and translucent.
- Drain and rinse the kidneys. Toss them in a dry frying pan over a high heat for 2–3 minutes, until they release their liquid, then tip them into a colander and discard the liquid.
- Add the kidneys to the casserole, season with salt and pepper and fry over a high heat for 3 minutes. Sprinkle over the flour and stir for 1 minute.
- Pour in the sherry and let it bubble for 1 minute. Add the water and bay leaf and simmer over a low heat for 10–12 minutes, until the sauce has thickened and the kidneys are tender. Turn off the heat and keep the casserole covered.
- Meanwhile, heat plenty of olive oil, about 2 cm deep, in a deep frying pan. Fry the chips in two batches for 8–10 minutes each, until golden. Drain on kitchen paper and season with salt.
- Sprinkle the parsley over the kidneys and serve with the chips.
