[EX Q]: CONTEXT: Foil is the way to go, combined with not too fierce a heat. You want to cook at about 160C until the centre of the pie is piping hot. To lower the chances of burning, portion the pie prior to reheating. That way the centre will get hot more quickly. Reheating more than once is generally not a good idea for safety reasons. You can however portion one night's pie and keep the other in the fridge. <sep> Q: How can I safely re-heat a chicken pie without burning the crust? A: Foil is the way to go, combined with not too fierce a heat. You want to cook at about 160C until the centre of the pie is piping hot
[EX A]: Could I use the microwave?

[EX Q]: CONTEXT: I would think this is happening because your cream is just about to turn sour. As cream ages, lactic acid builds up in it. The acidity in your coffee is enough at that point to push the cream over the edge to curdling. Try newer cream or a very low-acid coffee with old cream and you should be OK. <sep> Q: Why is cream curdled in coffee? A: I would think this is happening because your cream is just about to turn sour Q: Could it have something to do with either the coffee being too hot or the creamer being too cold? A: As cream ages, lactic acid builds up in it
[EX A]: Why would it happen with soy milk as well?

[EX Q]: CONTEXT: When you find cheap lemons, buy a lot. Squeeze half a lemon in each of the cavities of an ice tray. Freeze. Within a day, remove the frozen slivers from the tray to a ziploc bag in the freezer. You now have measured units of fresh lemon juice you may use for cooking and will keep for months. The frozen lemons are a bit less acid than fresh juice, but full of flavor. You can do the same with limes. <sep> Q: Are there any reasonable substitutions for lemon juice? A: You can do the same with limes
[EX A]:
What if I do not have limes either?
