[EX Q]: [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 Q]: [header] How to reduce acne using a tea tree face mask [title] Combine 1 teaspoon of raw, organic honey and 1-2 drops of tea tree oil in a bowl. [step] Put the honey in a clean bowl. Then, carefully pour the tea tree oil into the honey. <sep> (A) You may be using more than one tea tree oil. [substeps] If you are using the same amount of honey, one teaspoon is sufficient. (B) [substeps] It's best to use half tea tree oil for at least one week and once a week it should be reduced by 20 to 25 %. Do not use tea tree oil using the daily lotion, blush, or face powder. (C) Use a small spoon to mix the ingredients together. [substeps] If the honey is very thick, you can warm it up over the stove to make it a bit softer, but don't allow the honey to get too hot or you may end up destroying its antibacterial properties. (D) For detailed instructions, check the instructions for further instructions. Do not forget to mix and match the honey.

[EX Q]: [header] How to keep children from waking up too early [title] Identify possible reasons for your toddler's early wake time. [step] Many children wake up early in the morning due to noise, hunger, or light. Try to keep a record of your child's sleeping habits for one to two weeks. <sep> (A) This will help you provide a good, continuous record of his up-to-the-minute habits. [substeps] You might record breakfast, lunch, and snack times. (B) [substeps] For instance, if your child wakes up about an hour before naptime, have them break out his ready-made lunch so they can have enough time to eat before naptime. If your child usually wakes up hours before naptime, try a more gradual recording of their wake time. (C) Note what time your child goes to bed, what time they wake up, and any naps they take during the day. You should try to identify any patterns in your child's sleep, and if noise, hunger, light or too many naps during the day are causing the early wake time. (D) [substeps] Look on your child's waking times and things they engage in during the day and other times they wake up. You might note bedtimes, work/school times, break-ins, or other times that your child felt awake immediately.
