Question: I made a dish that used a small amount of wine and now I'm wondering how long I can keep the rest of it for next time. I know you wouldn't want to keep good drinking wine around long after opening it, but does the wine get too bad to use in cooking quickly? It's Chardonnay, if it matters. Thanks!

Question: Does anyone have any tips for roasting sweet potatoes? Since - seems to me - they cook and break down much faster than normal potatoes I skipped the parboiling stage and just stuck them (peeled) in the oven to roast for 45-60 minutes.However they still came out a somewhat soft and squidgy result. Roast for shorter time or some other methodology?I suppose I am looking for a crisp texture something like a normal roast potato but keeping the orange colour and distinctive sweet taste of the sweet potato itself.

Question: I'm making some saffron rice. After sautéing some onions and saffron and then toasting the rice, it calls for simmering with broth for 8 minutes with a parchment lid. What is the difference between a parchment lid and a top? Is it just the vent for steam? If so, can I just partially cover with a lid? Does the parchment need to be directly resting on the rice for it to "work"?note: I know what a parchment lid is, I just don't fully understand why you'd use one.
