Prepare rice according to package directions. When rice is ready, add milk, salt and sugar.  Bring to a boil, stirring frequently.  Lower heat and simmer 15 minutes, stirring occasionally.  

Add 1/2 cup hot pudding to eggs and stir well.  Pour egg mixture into remaining pudding.  Cook, stirring constantly until pudding thickens, about 1-2 minutes.  Remove from heat and stir in butter and liquor.  

Serve topped with hazelnuts and garnish with mint, if desired.
