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: I think grilling is probably a bad plan for duck legs; the fat content is a real danger like you said, and duck legs are tough enough you probably want to confit them or braise them.If you absolutely have to grill them, I would suggest confiting them at 200 degrees for three or four hours first (you could use veggie oil in a pinch) and then resting them in the fridge for a day or so in oil. As for finishing them on the grill, rinse them off gently, re-season if needed, cook flesh side down on a medium heat portion of the grill for a while until mostly heated through, then flip them over on a high heat portion of the grill to crisp up the skin, watching out for flares.  <sep>  Q: Tips for grilling duck legs? A: I think grilling is probably a bad plan for duck legs  Q: What would you recommend as a cooking method to make the meat tender? A: duck legs are tough enough you probably want to confit them or braise them  Q: How long should they be braised for? A: I would suggest confiting them at 200 degrees for three or four hours 
would you recommend any sort of glaze?

CONTEXT: There are good quality vegan margarines (Earth balance, Alsan) on the market nowadays, often they are of the interesterified instead of the hydrogenated variety. They are designed to behave and taste similar to butter instead of (as many cheap margarines seem to do) staying spreadable at temperatures where butter would be very firm. Unlike pure coconut or palm oil, they do not act very brittle when cold, and also they soften gradually instead of suddenly melting like eutectic solder. These should be on the top of the list of things to try...Also, some recipes recommend using more than one type of fat in pastry, for more interesting texture (eg such margarine, and smaller flakes of a hardened coconut fat).  <sep>  Q: Are there any butter alternatives for baking pastry? A: There are good quality vegan margarines (Earth balance, Alsan) on the market nowadays, often they are of the interesterified instead of the hydrogenated variety 
Would that give the dough the same consistency as when I use butter?

CONTEXT: Just an idea... I've had problems making foam because of hard/basic tap water (a lot of chalk in the water) - making frape though, not garlic foam:) Foam will more easily form in soft water as you can easily test with a piece of soap. If you have hard tap water you could try using boiled water (some of the chalk in the water will react and leave a residue on the bottom of the pot) or bottled water with pH 7 (neutral). Another idea would be to add just enough acid for neutralisation but I imagine that could be a bit tricky and you'd risk the milk curdling so I wouldn't recommend it.  <sep>  Q: Why was there not enough foam in my garlic foam with soy lecithin? A: Just an idea... I've had problems making foam because of hard/basic tap water (a lot of chalk in the water) - making frape though, not garlic foam  Q: This was my first attempt at making a foam using soy lecithin do you think that will help? A: If you have hard tap water you could try using boiled water (some of the chalk in the water will react and leave a residue on the bottom of the pot) or bottled water with pH 7 (neutral 

I got a bit of foam on top but there wasnt a lot of it. It felt like a waste of a lot of milk. How much foam should I be expecting?
