It appears that with the recent update the previous fix for the dried fruit cookbook has reverted to a broken state.

using notepad++ and this regex search:
(?![,\s]+Icon\s*=\s*\S*\,)[,\s]+Icon\s*=\s*\S

shows the follow two issues(Cookbooks.txt):
item HCCookbookdried
{
Weight = 0.5,
Type = Literature,
DisplayName = Dried Fruit Cookbook,
Icon = HCCookbook
TeachedRecipes = Dry Fruit;Store Dried Fruit in Bag;Dry Seeds;Store Dried Seeds in Bag;Make Baking Tray With Chopped Fruit;Remove Dried Fruit From Baking Tray,
ReplaceOnUse = HCCookbookdried,
}

item HCCookbookegg
{
Weight = 0.5,
Type = Literature,
DisplayName = Egg Cookbook,
Icon = HCCookbook;Make Scrambled Eggs;Make Scrambled Eggs with Cheese;Make Omelet;Make Vegetable Omelet;Boil Egg,
TeachedRecipes = Fry Egg,
ReplaceOnUse = HCCookbookegg,
}

- the comma is missing at the end of the icon entry for the dried fruit cookbook
- most of the recipes on the egg cookbook were entered after the icon entry but before the recipe list
