For the egg spread, start by hard-boiling the eggs. To do this, put the eggs, pierced with a needle, in boiling water for 10 minutes and then quench.
In the meantime, chop the onion and put it in a bowl. Add the softened butter, chopped parsley and the heavy cream cheese crackers as well and stir well.
Peel and chop the fully cooked eggs and stir them into the mixture as well. Season with salt, pepper and curry and also add the mustard and stir the egg spread well and serve.
