There are nearly as many ways to get the bitter tannins out of the acorns as there are people who eat them, which is to say, um, at least a dozen. Different species of acorns also taste different, and will act differently in the kitchen. Some are oily, some more floury, some light, some dark.
Rather than being grumpy at the weather- why don't we take a second to admire it? And think that while we may not like it, there are many creatures who do. Many plants that enjoy the rain or trees that yearn for heat to stop the rot that creeps up their trunk... Just think about it.
