Ice Blocks cooling Cellars down

[Pearilous]

I think cellars should be able to be affected by glacier ice (and other forms of ice if you can get 'em) to make them colder, making food last even longer inside. This would be nice for during winter, where it can sometimes be better to keep your food outside the cellar, so that it could be just as good (if not better) to keep your food in a cooled cellar.

Take a look at Medieval Expansion then. It has a cellar ice mechanic for cooling down cellars, and uses Glacier ice and lake ice to craft cellar ice.
