Grind the blue poppy in portions, it is best in the coffee grinder. Do not grind too long, otherwise the poppy seeds will get hot and bitter. Pour each directly into the milk.
Then grind the sugar, salt together with the vanilla pod in short pieces, finally the rice pudding (side effect: the coffee grinder becomes clean and tasteless again).
Bring to the boil briefly while stirring, allow to swell on the switched-off plate.
Stir in rum when the mixture is only lukewarm. Can also be replaced with suitable juice or coffee.
For cakes and muffins I use the mixture like this, as a filling for yeast wreaths or my poppy seed ring cake I stir in 2 eggs, then about 200g ground nuts or almonds until the mixture is dry enough.
The amount is enough for 1 cake or 12 muffins and a wreath or Hupf filling. Can be stored in the refrigerator for up to 3 days (without eggs).
