I'm trying to modify a recipe for a cake which calls for 3 cups of shredded butter nut squash. I thought I could replace this with roughly the same amount of pureed pumpkin (like what you would get in a jar).

However, the cake is still moist inside, after more than doubling the baking time it originally called for.

I don't mind that the consistency is too wet, I'm only concerned about cooking the eggs enough. Unfortunately, I don't have a thermometer to test the internal temperature. Is it safe to assume that at 350 degrees F, with the cake baking for more than 2 hours, that it reached the internal temperature of 138 degrees?

The cake is about 1.5 inches in height. I baked it for 1:10 minutes, then an extra 1 hour with tin foil on top (to prevent the top from burning). The top and bottom of the cake are not moist at all.

  • I would advise that you check your oven temperature with a good oven thermometer. Sep 23, 2010 at 23:47
  • While not answering the question directly - a comment on the substitution. You probably had far too much pumpkin. Shredded anything will have quite a bit of air in it. So I suggest if you try again you use just two cups or even less of the pureed as a "more equivalent" substitute.

    Yet another substitution note. The canned/jarred pumpkin is cooked and pureed, which is much more condensed than fresh shredded squash or pumpkin. I think a good starting point for a substitution is about 1 cup.

I can't see any possible way it didn't reach 138F inside after that length of time! I think you just had way too much liquid.


Unless you are very young, very old, or immunocompromised in some way (chemotherapy, leukemia, HIV, etc), slightly undercooked eggs are fine.
