Mix milk, baking powder, honey, sugar and salt in a pot, bring to the boil and simmer for 30-45 minutes, stirring continuously. To test, remove some cream and let it cool down briefly on a plate.
The cream is ready when it has a thick creamy consistency. Pour the cream while still hot into clean screw-top jars with lids and close them immediately. Let it cool down. Keeps in the refrigerator for 3-4 weeks.
