Given a paragraph about cooking, and a set of conversational question answers about the paragraph, generate a relevant question to the topic of the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`.

CONTEXT: Nutrition itself is off-topic. However, keep in mind the following:There are many compounds in tea leaves and some dissolve early, and some a little later. At some point (around 5-10 minutes of steeping at ~95Â°C), you will lose majority of the 'good stuff' and continue picking up less desirable compounds. You will notice that while colour might persist, the taste will be come less and less desirable. In some cultures re-using tea leaves is considered a faux-pas because of this.If you find your tea to be too strong after steeping, the best thing is to reduce the amount of leaves for the next time; as opposed to steeping them multiple times.  <sep>  Q: Steeping green tea leaves - how many times can I steep them, and do they lose flavanoids over steeps? A: At some point (around 5-10 minutes of steeping at ~95Â°C), you will lose majority of the 'good stuff' and continue picking up less desirable compounds 
How many times can I use the same tea leaves?

CONTEXT: Rinse the salsify first before using, that will help.Use a sharp peeler. Ive found that dull peelers create a lot more sap.as soon as you have peeled it, drop the salsify into acidulated water ( water + lemon juice). The acids help prevent the color change that occurs. Also wipe up the area with a damp cloth as you work. This will keep things clean and prevent your hands and everything you touch getting tacky.  <sep>  Q: How to prepare salsify (schwarzwurzeln) to minimise sap? A: Rinse the salsify first before using, that will help.Use a sharp peeler. Ive found that dull peelers create a lot more sap 
Do you know what the best peeler is to use?

CONTEXT: They're good pretty much forever. There is not enough available water for things to grow in there. Mind you, the more aromatic and subtle parts of the flavor will dissipate over time. The sugar absorbs water, giving the combination a very low water activity, meaning there's little water available for microorganisms to use in growth. As long as your flavoring pieces are small and well mixed with sugar they will not spoil.  <sep>  Q: How long is sugar (mixed with minor ingredients) good for? A: They're good pretty much forever. There is not enough available water for things to grow in there  Q: I mixed them over a year ago, would it still be good? A: As long as your flavoring pieces are small and well mixed with sugar they will not spoil 

Some I mixed with lemon/orange zest, will that pose a problem?
