1- Thoroughly wash your watercress. Pick few nice leaves, blanch them and put them aside to garnish your soup at the end.
2- In a thick bottom saucepan, melt the butter down and gently sweat off your shallots for 5 minutes or so.
3- Coarsly chop your watercress and add them to the shallots, season well and allow to gently cook for 5 minutes. Finally pour in the milk and let the mixture cook for 8 minutes.
4- Let the mixture cool down for a little while and blitz the watercress-milk mixture in a food processor. Then pass it, through a fine chinois making sure to make most of the watercress's pulp pass through.
5- Put your double cream in the freezer for 5 minutes.
6- Mix your watercress pure with the yoghurt, taste the seasoning and put the mixture in the fridge for another couple of minutes.
7- Whip your double cream, season it well with salt and pepper.
8- Pour some of the watercress soup in your soup bowl. Using a piping bag, add a bit of whipped cream on the top of the soup. Sprinkle a bit cayenne pepper on the top of it. Finally top the whipped cream with a couple of blanched leaves of watercress.
