Q: I need to grease a baking pan (which I don't have) for brownies. I also don't have butter or shortening. I do have one of those pyrex oven safe glass pans and something like a small dutch oven, but with a glass top instead. Could either of these substitute for baking pan instead? And in lieu of the butter, could I use vegetable oil and a paper towel to grease one of the pans that I do have (without affecting the final results of the brownies)?

Q: Is there a special tool available just for cracking open pistachio nuts? I'm asking because as I have gotten older, I have developed severe arthritis and joint pains, making opening them with my fingers very painful. I've always loved pistachios and hate having to ask my wife to crack them open for me.I have tried using regular nut crackers, but the pistachio either slips out without cracking or the nut inside gets crushed.
