What are the ingredients in Cole’s life cake?

From the text:

One by one he sampled each item , tasting first the flour, sugar, and baking soda. He purposely took big mouthfuls to prove nothing bothered him . Casually he drank some thick molasses. He stared straight at Garvey as he bit off a chunk of butter and swallowed it. When he came to the eggs, he picked one up, tilted his head back, and broke it raw into his mouth. He downed it with a single swallow. He finished by shaking salt directly into his mouth.
