Cut the vanilla pod open lengthwise and scrape out the pulp with the back of a knife. Bring milk, sugar, honey, salt, baking soda, vanilla pod and pulp to the boil in a saucepan. Simmer the milk cream at low heat for approx. 1 1/2 hours, stirring constantly and taking care that the milk does not boil over.
The milk cream is ready when it has a thick consistency and is boiled down by about half. Pour the cream into clean, hot-rinsed twist-off glasses and close them tightly. Turn glasses upside down for about 15 minutes, then turn them over and let them cool down.
Milk cream is best stored in the refrigerator. Once opened, the cream can be stored for approx. 3 weeks, without interruption for several months.
