LH 70: Is Canned Cake Safe?

Why you should not bake and seal a cake in a jar

In this week’s episode, I answer a question from a listener named Sharon. She wants to know if it is okay to make “canned” cake.

Let me make sure you know what Sharon means…

Every year especially around holiday time you’ll see these recipes floating around the internet. It’s for canning cake or canning bread.

First, it’s called “canned” but it’s not processed in a canner. It’s baked.

Second, we’re not talking about bread exactly. It’s really like a tea bread such as pumpkin bread or zucchini bread.

A “canned” cake recipe calls for baking this bread or cake in the jar and then pulling it out of the oven and putting on a lid and a ring. As the jar cools, it makes a seal.

Yeah…DON’T do this.

Every year, some well-meaning canners think they have the safety portion figured out. But unfortunately, the research shows otherwise.

I know it sounds nifty, but it turns out…its not really a safe practice.

In this episode, I dive deep into the how the research was done, what was discovered and how the oven didn’t do what you’d think it would do.

You’ll learn:

  • Why canners argue about this type of recipe
  • Why you might find it in some cookbooks
  • What sort of research was done on this practice
  • What the research means
  • The science behind the research recommendations
  • How the oven doesn’t kill what you think it will
  • How commercial companies can get away with it
  • What is currently recommended you do instead
