Answer:
The poem is an extended metaphor about people who fall in love with each other but end up breaking up for being too different.
Explanation:
The speaker in the poem uses the pie as a metaphor. The way he likes his pie shows what kind of person he is. However, the girl he falls for is way different from him - she does not like the pie with spice the way he does. That is why they cannot be together. In the end, the speaker asks someone, an unknown "you", if that person would like a piece of pie. He is basically offering his heart, his love, to someone who may be just like him - someone who likes a spicy pie.
