For the mayonnaise
3 free-range eggs, yolks only
1 tsp English mustard
½ lemon, juice only or 2 tsp white wine vinegar or cider vinegar
300ml/10fl oz light rapeseed oil
sea salt and freshly ground black pepper
For the beetroot
200g/7oz raw beetroot
2 tsp red wine vinegar
pinch salt
3 tsp sherry vinegar
1 shallot, finely chopped
1 garlic clove, finely chopped
1 tsp chopped thyme
salt and freshly ground black pepper
4 tbsp olive oil
For the scallops
4 rashers smoked streaky bacon
12 scallops, cleaned and corals removed, the scallop meat diced into 5mm/¼in pieces
1 apple, peeled, cored, cut into 5mm/¼in dice
1 shallot, finely chopped
2 tsp finely chopped gherkin
2 tsp finely chopped chives
sea salt and freshly ground black pepper
To serve
4 slices sourdough bread
handful rocket leaves
lemon wedges
½ quantity mayonnaise, from above
For the mayonnaise, put the egg yolks, mustard and lemon juice or vinegar into a bowl and whisk together for one minute. Now gradually add the oil, drop by drop to begin with, then in a steady stream, whisking constantly, until the mixture is emulsified and thick.
Alternatively, you can make the mayonnaise in a blender or food processor, blending the egg yolks, mustard and lemon juice or vinegar for one minute and then adding the oil slowly through the funnel with the motor running.
Season the mayonnaise with salt and pepper to taste. Cover and refrigerate until ready to serve. It will keep in the fridge for a couple of days.
For the beetroot, place the beetroot in a saucepan, pour on water to cover and add the wine vinegar. Bring to a simmer, add a pinch of salt and cook for 25 minutes.
Leave the beetroot to cool in the water until you are able to handle it, then remove and peel off the skin. Cut the beetroot into 1cm/½in dice, using a sharp knife.
Place in a bowl with the sherry vinegar, shallot, garlic and thyme. Season with salt and pepper and drizzle over the olive oil. Mix well and then cover and leave to marinate for at least two hours.
For the scallops, preheat the grill to high.
Lay the bacon on a grill tray and grill on both sides until very crispy. Allow to cool down and then chop the bacon into small pieces.
Put the scallops and apple into a bowl with the shallot, gherkin, bacon and chives. Add two teaspoons of mayonnaise and mix well. Taste for seasoning and add salt and pepper as required.
To serve, toast the bread on both sides and place on four serving plates. Spoon the scallop tartare neatly on top. Spoon some of the marinated beetroot with a little of its dressing alongside. Scatter over the rocket and serve with lemon wedges and mayonnaise in a bowl on the side for guests to help themselves.
