- 500g/1lb 2oz very fresh tuna loin, trimmed
- 2 tbsp olive oil
- 1 loaf sourdough bread, sliced
- 1 shallot, finely diced
- pinch Dijon mustard
- ½ lemon, juice only
- 4 tbsp chives, finely chopped
- Place a piece of cling film on the work surface and place ž of the tuna on top. Place another piece of cling film on top and, using a rolling pin, hit the tuna until it is very thin.
- Remove the top piece of cling film. Place a 20cm/8in diameter plate over the tuna and cut round it. Flip everything upside down so the plate is on the bottom.
- Heat a frying pan and add the oil, once hot add the sliced bread and cook on each side until crisp.
- Remove the remaining cling film and lay the toasted sourdough over the tuna.
- Place a serving plate on top, upside down. Flip the plates over, so the tuna is on top of the bread, on the serving plate.
- For the tuna tartare, finely dice the rest of the tuna and place in the bowl with the shallot, mustard, lemon juice and half of the chives.
- To serve, garnish the tuna carpaccio with the tuna tartare and the rest of the chives.
