I love the chapters where the entire premise for the ingredient is just some unhinged past trauma healed with the magic of food.
If he hates apple pie cause it reminds him of his mom (who couldn't call him or explain? WTF is the dad's excuse in this?) why the fuck does he keep ordering it? Who cares. Anyways, check out these apples.
Well, he hates it because it doesn't remind him of his mother's. That's the whole point. He wants his mom's apple pie and apple tea because he grew up with it and with her having divorced his father, he can't get it... He's ordering it because he wants to find the flavor he remembers...
I didn't want to comment on this chapter because I have a very similar situation that happened to me, but the hell with it. For me, it was my father, and it was just after I was born, rather than when I was an older kid, so I very much understood his anger... And I had some issues with this chapter, that's all I'll say.
