Example Input: [header] How to use a vanilla bean [title] Split the pod if you want to use the seeds.

Being too cold will crush the seeds as they break into the batter. (B) [substeps] Removing the seeds can make it easier to infuse the pod with a natural vanilla flavor. A good rule of thumb is to reserve about cup (100 g) of pod before you can drink the rest. (C) [substeps] Keep in mind that you will not be able to extract the seeds directly from the pod if you plan to use it. Instead, you will be mixing the seeds into the flour.

(C) [title] Use the newspaper to wipe and scrape any soot out of the cast iron burner. [step] Do this several times until any soot is gone.
