It is amazing how well vanilla and rye go together. We added 30 grams of rye to our vanilla ice cream base and it amped up the flavors of the vanilla and the sweet dairy. It added a richness and complexity to the base. Until we made it we did not know what we were missing. Since making this ice cream we have used rye as a seasoning in other applications from lobster stock to marinating steaks. Perhaps it is not the vanilla rye combination that just works. It may be the developed flavors of the rye which compliments and enhances many other ingredients.
