  • 40 g butter
  • 700 g calves' liver, thinly sliced
  • plain flour
  • seasoning

For the caramelised onions

  • 3 large mild onions
  • olive oil
  • granulated sugar

For the gravy

  • 20 g butter
  • 20 g plain flour
  • 450 ml beef stock
  • 1 1/2 tsp soy sauce
  • 1 1/2 tbsp balsamic vinegar
  • a little gravy browning


1. Set the oven to 220°C/gas 8.

2. Peel and thickly slice the onions into rounds 1 cm thick and arrange on a well-greased baking sheet. Brush the onion slices with olive oil and a little sugar to caramelise. Cook for about 30 minutes, turning and seasoning half way through.

3. Meanwhile, heat a non-stick frying pan until very hot, adding the butter. Toss the liver in seasoned flour, add to the pan and cook over a high heat for 1-2 minutes on each side until browned all over and just done in the middle. Lift out the liver and keep warm.

4. To make the gravy, melt the butter in a small pan, blend in the flour then add the stock and bring to the boil. Add the soy sauce, balsamic vinegar, gravy browning and seasoning.

5. Serve the liver with the caramelised onion rings, balsamic gravy and creamy mustard mash.
