This specifically would be more for farmers delight related items, but the ability to mark certain foods as warm like soup or hot chocolate would be really nice since you could drink them to give you a status effect or bonus to fight against the cold. Even a similar system to scorchful where certain foods/drinks could warm you up more or less.

Hey there, just like in Scorchful, there are already tags for this in Frostiful, and they are also documented on the wiki: https://github.com/TheDeathlyCow/frostiful/wiki/Config#items

Farmers delight should already be included unless the new version changed item IDs around
