I want to experiment with a cream pie with a nonbaked filling (containing whipped cream, thickened with gelatine - basically a flavored diplomat cream). But for aesthetical reasons, as well as a better crust-to-filling ratio, I want to try it with a lattice. But I don't have much experience with double-crust pies, so I am not sure how to make it.   My first idea is to blindbake the double crust, then remove the "weights" and get the filling somehow into the pie. I normally use white beans as weights. But I am not sure how I can get them out without breaking the lattice, as they are quite heavy. Also, I normally line the crust with alu foil when blindbaking. How can I get the alu foil out, and how can I prevent the beans from sticking to the lattice? I don't think there will be problems with the filling, I think a piping bag can get it in while still semi-liquid.   The second idea is to bake the lattice separately. I would weave it, put it on something of the right size (I have a glass cake pan bottom, could use it without attaching the pan wall) and bake. Blindbake the low crust, then fill the pie, then cover with the lattice. The question is, how to attach it to the pie?   Has anybody tried this before? I think that the second idea is more feasible than the first, any comments? Or are there other tricks I haven't thought of? Any reason why this will or won't work?  
Coffee in a container is approximately as safe as boiled water in a container. While it may be unpleasant tasting, the water in coffee and tea is almost universally boiled, and the scalding liquid is placed directly on the grounds/tea leaves. There is a little nutritional value in coffee and tea extracts, providing some support for new microbes introduced after the boiling, but not much.  There is no reason to be wary of coffee kept in a clean, sealed container for a day.
