Preheat your oven to Th.6 (180° C). In a saucepan, pour the water, milk and chicken stock. Once melted, make the puree according to the instructions.
Cut the ham into thin strips. Separate the egg yolks from the egg whites. Mix the yolks and the grated cheese with the puree. Beat the egg whites until very stiff, then gently fold them into the preparation. Add the ham.
Generously butter ramekins or soufflé molds and pour in the mixture. The molds should be filled 3/4 full.
Put in the oven and bake for about 20 minutes without opening the oven door, this would prevent the soufflés from rising. The soufflés should brown gently. Serve immediately
