Wash and peel the asparagus and cut off the woody ends. Cut the asparagus spears in half. Boil up about 1.5 litres of salted water in a wide pot. Add 1 pinch of sugar and cook the asparagus for about 7 minutes
Cut the leek half lengthwise and wash thoroughly. Cut the leek into thin rings. Cut ham into small pieces. Heat oil in a pan. Lightly fry the leek and ham in it, season with salt and pepper. Take out and distribute on 4 small or 1 large greased casserole dish. Drain the asparagus and place on top
Wash the chives, shake dry and cut into small rolls. Mix eggs, chives and cream, season with salt and nutmeg. Pour the egg cream over the asparagus and bake in a preheated oven (electric range: 175 °C/ convection oven: 150 °C/ gas: level 2) for 20-30 minutes until golden brown. Take out and serve immediately
