In a large bowl, combine the strawberries, tomatoes, roasted red pepper, shallot, garlic and sherry vinegar. Toss all the ingredients together then leave to infuse overnight.
The next day, add the extra-virgin olive oil to the bowl and whizz everything together with a hand blender or in a food processor until smooth, adding a splash of water if it’s too thick. Season the gazpacho to taste with salt and pepper.
Pour a little olive oil into a frying pan over a medium heat and fry the sourdough croutons for 4 to 5 minutes, until golden on all sides. Drain on kitchen paper and sprinkle with sea salt.
Divide the gazpacho between individual soup bowls and garnish with the extra strawberries, basil leaves, edible flowers and sourdough croutons.
Finish with a drizzle of extra-virgin olive oil and some sea salt.
Serve with a cold glass of sherry, preferably amontillado or palo cortado.
