[header] How to make chickpea chocolate chip cookies [title] Gather your ingredients and supplies. [step] It may seem like a silly step, but if you do this first, it will save you time later and help you get everything done much more quickly. Because everything you need will be in one place, you don't need to waste time rummaging through cupboards. <sep> (A) Once you've compiled your supplies, get down to baking. If you don't have everything in one place, make sure your fridge is large enough to house everything you're going to need. (B) [title] Melt your chocolate chips in the microwave for about 5 minutes. [step] Melt the chips like you usually would. (C) [title] Open the can of chick peas and dump them into your colander or strainer. [step] Rinse them well and place them into the food processor. (D) Try to gather your ingredients and supplies only. If you don't have everything this is likely not for you.

Ex Output:
C


Ex Input:
[header] How to use a vanilla bean [title] Split the pod if you want to use the seeds. [step] If you are planning to use the vanilla bean in a batter for a cake or for a batch of cookies, you will need to open the vanilla bean pod and remove the seeds. You will then add the seeds to the batter to infuse it with a natural vanilla flavor. <sep> (A) [substeps] [substeps] Wait a few minutes before parting the pod or moving it to a serving dish. 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 ½ 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. (D) [substeps] To split the pod, lay the vanilla bean pod on top of a clean, dry cutting board. Turn the hooked end of the vanilla bean to the top of the board.

Ex Output:
D


Ex Input:
[header] How to divide ferns [title] Water the fern generously two days before digging it up. [step] Make sure your fern is well-hydrated as the plant's ability to absorb moisture will be diminished for a week or two after it is divided because its root system will be compromised. [title] Dig up an outdoor fern with a shovel. <sep> (A) [step] Do this after it has been removed, and fill the trench or pit just below the fern's roots with soil, spray it down with topsoil, and shake gently to loosen any rocks. Add a couple of drops of ammonia or rubbing alcohol. (B) [step] Push the shovel straight down into the soil about 6 inches away from the fern stems, all the way around the fern. Then, push the shovel in again and lift the fern up out of the soil on the tip of the shovel. (C) [step] A plastic or a rubber shovel will work the best. Dig up as many ferns as you want. (D) [step] You can use a coarse hardwood spoon to do this. Only dig up the roots, not the leaves or stalks.
