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:`.

[EX Q]: CONTEXT: First off, the ISO standard is not intended to produce a good cup of tea. It is designed to produce a consistent one for taste testing, so that no tea manufacturer can claim that his tea wasn't made "properly".It's title is "Tea -- Preparation of liquor for use in sensory tests"As for the actual tea making, yes, leaving the bag in longer will make a stronger cup of tea. The concentration of caffeine (along with flavour molecules and everything else) will slowly trend towards an equal concentration in the leaf and in the water. The longer you leave the tea bag/leaves in the water, the closer to equilibrium you will get.There are other factors that affect this, such as the temperature of the water, cut of the leaves, bag versus loose leaf and so on, but the trend is always towards equilibrium as time progresses.I'm not sure where the upper limit of this lies, but I think that once the cup is cold there's no point in it anyway. Thus, leaving the bag in for an hour is a bit much. I usually steep my tea for 3-6 minutes, depending on how strong I want it to be.  <sep>  Q: Does brewing tea for longer result in higher caffeine content? A: The concentration of caffeine (along with flavour molecules and everything else) will slowly trend towards an equal concentration in the leaf and in the water 
[EX A]: The ISO standard is 6 minutes when does the concentration equal?

[EX Q]: CONTEXT: I'm not a professional fudger, but here is my theory: one should add it to the boiling mixture. The reason is that butter has milk solids that are said to âburnâ at low temperatures (somewhere in the range 120C-150C or 250F-300F) which just above the soft ball stage (113C or 235F) needed for making fudge. I interpret the burning to mean that those milk solids (sugars and proteins) get a chance to contribute to the Maillard reaction that gives caramel (and its grained cousin the fudge) its great and rich flavor. Given how unique and varied the flavors arising from butter are, I would not want to miss their contribution by adding them after the heat is gone.  <sep>  Q: Butter usage in fudge? A: I'm not a professional fudger, but here is my theory: one should add it to the boiling mixture  Q: I have a number of questions relating to fudge. Thank you in advance for your help. A: The reason is that butter has milk solids that are said to âburnâ at low temperatures  Q: My main question here is Why do some recipes put the butter ON the fudge once its hot whereas the professional videos (i.e. youtube mackinac fudge shops) seem to show the butter in the boiling mix? A: I interpret the burning to mean that those milk solids (sugars and proteins) get a chance to contribute to the Maillard reaction that gives caramel 
[EX A]: Use of whipping cream in fudge, Why is my chocolate fudge not that dark?

[EX Q]: CONTEXT: I make bacon and other cured meats frequently. I find that the amount of liquid released from pork belly varies. That is not a useful measure of how the cure is proceeding. Bacon, in particular, is usually cooked after the cure, so I don't worry too much. I use the salt-box method, coat the belly in cure mixture, place in large zip lock, place in container slightly larger than belly and put in fridge. Flip every day or so for a week. What I look for next is a firming up of the belly. I pinch it. If it has firmed up after a week, I move on to hot smoking (or you could use your oven). If it still feels soft, I give it another day or two.  <sep>  Q: How much juice should come out when I'm curing pork belly? A: I find that the amount of liquid released from pork belly varies 
[EX A]:
My latest batch has extracted less than half of the juice of the first two. Is this normal?
