Halve the vanilla pods lengthways and scrape out the pulp. Bring the pulp with the almonds and cream to the boil in a saucepan. Simmer everything for a few minutes, then let it cool down.
Pour the almond cream through a sieve into a container. Beat the egg yolks with the sugar until frothy. Carefully add the mixture to the almond cream. Pour in the grain or vodka in a thin stream while stirring. Close the jar tightly and let it steep in the refrigerator for about 10 days.
Filter the mixture, pour it into a well-cleaned bottle that has been rinsed with boiling hot water and close it. Can be kept in the refrigerator for approx. 3 weeks
