For the mayonnaiseFinely chop the garlic clove. Whisk together the egg yolks, a squeeze of lemon juice, the Dijon mustard, smoked paprika, the chopped garlic and salt. Start whisking in the olive oil gradually. Continue until the mayonnaise is thick. Season with salt and cayenne pepper.
For the guacamolePeel and finely dice the red onion and garlic. Finely dice the red chilli. Cut the cherry tomatoes into quarters. Pick the coriander leaves and roughly chop. Cut the avocados in half, remove the stone, remove the skin and then cut the flesh into large chunks.
Mix the avocado with the red onions, chilli, garlic and cherry tomatoes. Season with Maldon sea salt and squeeze on the lime juice. Mix well to break up the chunks of avocado and add the coriander leaves.
For the prawnsPrepare the prawns by removing the head and the shell. Make an incision along the spine with the tip of the knife to remove the black digestive tract.
Peel and dice the garlic clove, chop the parsley.
Heat a frying pan until hot and add a splash of olive oil. Add the prawns. When they are almost cooked add the remaining garlic, parsley, lemon juice and season with salt and pepper.
Whilst the prawns are cooking fill the glasses with guacamole. Top with the prawns and finish with a quenelle of mayonnaise.
