[Q]: CONTEXT: Can't comment on the nutritional side of things, but the main reason I can think of for not always including it is that it has a slightly different flavour. A much more intense lemon flavour is provided by the zest while the juice has the more tart elements (and of course water).If you're just interested in avoiding waste, you can freeze the zest. <sep> Q: Are there any reasons not to include the zest when citrus juice is an ingredient? A: the main reason I can think of for not always including it is that it has a slightly different flavour Q: How does the zest change the flavor? A: A much more intense lemon flavour is provided by the zest <sep> FOLLOWUP_Q: Is it the same for all citrus fruits?
[A]: the juice has the more tart elements (and of course water

[Q]: CONTEXT: If it's refrigerated, it'll last for at least a week, as long as you didn't pre-dairy it. Unrefrigerated, I wouldn't trust it for more than a day. Coffee is a crappy growth medium and it should start out the next best thing to sterile, but, even covered, its going to start to get moldy.Obviously if you add dairy, then you're dealing with that dairy shelf-life, and that isn't very long at all. <sep> Q: How long is it safe to drink coffee after brewed? A: Unrefrigerated, I wouldn't trust it for more than a day. Coffee is a crappy growth medium and it should start out the next best thing to sterile, but, even covered, its going to start to get moldy <sep> FOLLOWUP_Q: Should it be refrigerated?
[A]: If it's refrigerated, it'll last for at least a week, as long as you didn't pre-dairy it

[Q]: CONTEXT: Fudge is basically a chocolate flavored candy.You combine chocolate and a sugar syrup and boil the syrup until you get the desired concentration. Everything else about the recipe is to either minimize sugar crystal size or add flavor.Sweetened condensed milk will do two things-1- give you a nice, caramelly flavor2- Save a little time. Since it has less water to begin with there will be less to boil off. <sep> Q: Can I make fudge with regular milk? A: Everything else about the recipe is to either minimize sugar crystal size or add flavor Q: would condensed milk change the flavor? A: give you a nice, caramelly flavor <sep> FOLLOWUP_Q: How would it change the texture?
