Anas liked Gourd because Mohammad liked Gourd

Volume 3, Book 34, Number 305:
Narrated Ishaq bin 'Abdullah bin Abu Talha:
I heard Anas bin Malik saying, "A tailor invited Allah's Apostle to a meal which he had prepared. " Anas bin Malik said, "I accompanied Allah's Apostle to that meal. He served the Prophet with bread and soup made with gourd and dried meat. I saw the Prophet taking the pieces of gourd from the dish." Anas added, "Since that day I have continued to like gourd."

Hmmmmmmmmmmmm...

Did Anas like Gourd because Mohammad like Gourd, or because he liked the Gourd himself?

If it is because of Mohammad, was this inserted into the Hadiths as a subliminal message to all followers of Mohammad to like whatever Mohammad liked?

If the answer is because he liked Gourd himself, why is this passage in the Hadiths at all? Was it to show that Mohammad liked Gourd, or was Anas a Gourd salesman?
