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:'.

[Q]: CONTEXT: I understand that sugar (and by extension jaggery) helps yeast multiply at a very fast paceThis is only partly true. Yeast is a living organism and can only live under certain conditions, including a certain osmotic pressure. If you start from pure bread dough, then adding a bit of sugar to the dough (or to the preferment) can make it rise faster. But adding sugar in quantities sufficient to make the bread taste sweet will slow down the yeast growth, as opposed to making it quicker. There is even an upper limit for how much sugar you can add per 100 g of flour, and it's not recommended to use recipes which prescribe more, as they turn out poorly. So I wouldn't change the amount of yeast, unless you make the empirical observation that your yeast is overfed (recognizable by speed of raising and the changed smell). <sep> Q: Should I decrease the amount of yeast I add depending on how much sweet I add (I use jaggery) while making sweet bread? A: adding sugar in quantities sufficient to make the bread taste sweet will slow down the yeast growth, as opposed to making it quicker
[A]: So is there a rule or ratio by which I must decrease the yeast for every unit of sugar added?

[Q]: CONTEXT: You cooked it at too low a temperature. Sous vide is intended for meat where you want the protein to remain tender. It shouldn't have any sinews. Think chicken breasts, or the long filet along the spine of a pig. This meat gets nicely cooked at 60-65C (depends on the animal), and tough and dry above that. Meat marbled with sinews has to be cooked at a temperature where the sinews (collagen) melt into gelatin. This happens at about 70C at least, and takes hours. Since the muscle fibres are already toughened at that temperature, there is no reason to hold it low; you can put it at full boil in a normal pot and cook it there, you just have to wait long enough. In theory, you could do it in a sous vide bath too, but you won't get any of the benefits sous vide gives to tender meat. <sep> Q: I tried cooking sous vide chicken and it came out tough and stringy, can you tell me why? A: Sous vide is intended for meat where you want the protein to remain tender. It shouldn't have any sinews Q: I tried cooking it at 60C, is that the correct temperature? A: This meat gets nicely cooked at 60-65C (depends on the animal), and tough and dry above that
[A]: How long should I cook chicken breasts at that temperature?

[Q]: CONTEXT: Yes that's exactly what it means, apply salt to the steak. You shouldn't coat it, but you should apply salt very liberally. It's actually hard to over-salt a steak; many inexperienced cooks actually underseason the steak.I suggest about 1 tsp per side for a good ribeye. Salt it about 10-15 minutes prior. <sep> Q: What does it mean to 'salt' a steak prior to frying? A: exactly what it means, apply salt to the steak. You shouldn't coat it, but you should apply salt very liberally
[A]:
Should I let it sit with the salt before cooking it?
