1st, mix whole milk powder with water in a bowl
Place half cooked rice in a pot, non stick if you have, then pour in 1/4 c of milk, cook on low-medium heat
While cooking, stirring continuously, while adding milk a ladle at a time. Continue cooking and adding milk, until rice is fully cooked
Take off from heat, add in yolks, stir in butter wooden spoon
Add in vanilla sugar, sugar, butter, mix well
Beat egg white until stiff then add into rice mixture, stir
Add in raisins, stir well
Dump mixture onto parchment lined rectangular pan
Sprinkle with crumbs
Bake on preheated 350 F for 40 mins
Serve with your sauce or syrup, if you like (I like resting it for a couple for hours on the fridge, sugar with settled and sweet enough without any sauce or syrup!)
