I'm aware that one can't normally talk directly about others' feelings in
Japanese i.e.:

> 母はすしを食べたい *  
>  母が寒い *

should be something like

> 母はすしを食べたがっています  
>  母が寒そうだ

Does this apply to 好き? 「母はすしが好きです。」sounds OK to me but I'm not sure.

question
grammar
Can you use 好き about someone else's feelings?
The sentence should be correct. In the basics of Tae Kim's guide, when
introducing adjectives, one of the examples given is:

> ボブは魚が好きだ。

Which corresponds well to your example.

answer
母はすしが好きです is perfectly fine.

食べたがる and 寒そう are describing one's temporary appearance. You can think ～がる is
like "showing signs of ～". On the other hand, ～が好き is a simple fact rather
than a temporary "sign".
