Without any ceremony or pomp, combine all the ingredients and cook them in a crockpot on medium or low for at least 4 hours. Cooking it on the stove or on high in the crockpot can get the job done faster, but you'll have to give up some of the savoury richness that comes from letting maize soak in dairy for so long.
The cream cheese slices should all be fully melted so that they can easily crumble and mix with the cream and butter to create the gravy. Don't salt your food excessively. The butter and cream cheese are both very salty. Salting the food too much will destroy it. Please consult the recipe on recipezaar from which this recipe was developed if you prefer a lighter version of it.
