In a hot dry skillet toast the crushed coriander and caraway seeds until fragrant 1 minute max whilst constantly stirring to not let them burn. Take off heat.

In a small saucepan combine the heavy cream, the leftover milk, 80gr sugar, a pinch of salt and the toasted spices, stir, bring to an almost boil and leave covered to steep 1 hour. Then sieve the mixture, return it into a clean saucepan, reheat to an almost boil again, add the cornstarch milk and cook constantly stirring until thickened. Take off heat, add the cream cheese and the rye whisky, mix until smooth. Cool to room temperature then transfer to the fridge overnight.
