Georgina O’Sullivan’s best BLT
Makes 2

Ingredients

• 1 beef tomato
  
• salt
  
• 4 thick slices of streaky bacon
  
• 4 slices sourdough bread
  
• olive oil
  
• 4-6 cos leaves
  
• basil mayonnaise
• 1 avocado, peeled and sliced

For the basil mayonnaise

• 2 egg yolks
  
• salt
  
• scant teaspoon Dijon mustard
  
• 225ml sunflower oil
  
• handful chopped basil
  
• squeeze of lime juice

Method

1. To make the mayo, put the egg yolks in the processor with a little salt and the mustard. Very slowly – drop by drop – add the oil with the motor running. As the mixture begins to thicken, you can add the remaining oil a little faster. Add the basil and lime juice to taste. Keep in the fridge until serving.
2. Starting with the tomato, slice thinly with a serrated knife, sprinkle with salt and leave on a sheet of kitchen towel for 10 minutes to rid it of excess liquid – no soggy sandwich here!
3. Next, grill the bacon on a cast iron grill pan until cooked. Drizzle the bread with olive oil. When the bacon is cooked, remove it from the pan and keep warm, clean the pan if necessary and grill the bread on the same pan, on each side.
4. Place the toasted bread on the serving plate or board, cover with the lettuce, then add the sliced tomato, bacon, and avocado. Top with the basil mayonnaise and cover with the second slice of grilled bread. Eat immediately.
