'tea recipe' -- isn't it literally tea, milk, and sugar?
Also, I feel like the author didn't think about this very hard. The guy hates touching people, but he's all set to go make his name fighting? Fighting requires quite a lot of physical contact...

He can bear to do basic etiquette of holding and kissing someone's hand so he even though he feels disgusted by it he can hold it in, fighting wouldn't be that much of a problem.
And as a person who also hates physical contact and feels disgusted or uncomfortable by it (though not as bad as him) touching somoene while fighting is not as bad, it still feels disgusting but not to the same extent, and I assume they use swords more than fists, and with the heavy armor most of the skin is covered so maybe skin to skin contact wasn't extreme.
