4: In a small frying pan on medium heat, fry 2 slices cured ham on both sides. When well fried, transfer to a plate and let it cool, then cut into strips or small pieces. Set aside.
5: Use the same pan, still on medium heat, and add 1 slice bread cut into dice. Fry, stirring frequently, until golden brown all over, then set aside.
6: Melt 1 knob butter in a large frying pan on medium heat. When good and hot, add the sliced shallot. Salt and pepper, then fry for 1 minute.
7: Add the leeks and mix. Cover and cook for 3 or 4 minutes. The leeks should still be nice and green.
8: Add 200 ml cream, salt and pepper moderately. Turn down the heat and leave to thicken gently for a few minutes.
9: Add the fried ham and the eggs and mix together.
10: At the last minute, add the croutons (we want them to stay as crunchy as possible). Mix once more and serve.
Remarks
For a finer texture, you can roughly chop the hard-boiled eggs in stage 1. For a true bistro touch, drizzle with a little vinaigrette just before serving.
