Beat the eggs in a bowl with flour and milk. Add pepper and heat in a pan. Separately grind the pine nuts with the passum in a mortar. As soon as the egg mixture begins to boil, remove from heat. Add the passum and pine-nut mixture. Resume cooking over low heat for approximately 15 minutes, stirring so that no lumps form. Add honey and pour into 4 individual bowls to serve.
