Chilled Cucumber and Yoghurt Soup with Prawns

Description
My favourite soup on a hot summers day-I just love this. The prep time doesn't include chilling which I think takes about 6 hours.



Ingredients

 * 2 1/2 	 cucumbers
 * 300 	ml greek natural yoghurt
 * 300 	ml quality chicken stock (we use a canned Asian style)
 * 40 	ml sour cream
 * 3 	drops Tabasco sauce
 * 2 	tablespoons chopped fresh mint
 * 12 	large raw prawns, shells and heads removed
 * 2 	tablespoons olive oil
 * sea salt

Directions
Peel and deseed cucmbers-cut 2 into dice, and blend with the yoghurt, stock, sour cream, Tabasco and mint.

Chill until very cold.

Peel and deseed the remaining 1/2 cucmber and cut into small thin matchsticks.

Chill.

Before serving, saute prawns in the oil until they turn pink.

Sprinkle with the salt and serve them in the chilled soup immediately.

Serve the soup garnished with the strips of cucumber.
