It was back in 2011 so I can't remember exactly how it was besides enjoying it.
A page I found describes it as this:
'The same book details a recipe: the spiders are tossed in a mixture of MSG, sugar, and salt; crushed garlic is fried in oil until fragrant, then the spiders are added and fried alongside the garlic until "the legs are almost completely stiff, by which time the contents of the abdomen are not so runny."'
Turns out people started eating them there out of desparation due to food shortages and they became some kind of delicacy now.
