Mix together the crème fraiche, paprika and basil, check the seasoning and set aside.
Cook the chicken.
Make a batter with the cornflour, baking powder and sparkling water until it’s the texture of single cream.
Dip the courgettes in the batter and deep-fry in batches until crisp. Sprinkle with the salt and paprika. Drain and assemble the sliders with the chicken, lettuce, gherkins and chillies then top each with a dollop of the crème fraiche mixture. Stick some spikes in the top to hold this delicious mixture together, you don’t want the sliders sliding.
Serve with the hot courgette fries, extra chillies and napkins.
