Time for a snack

I never understood the appeal of eating sunflower seeds. Too much work for a nebulous (imaginary?) reward. I have the same feeling about eating these little mussels dredged up from the bottom of riverine waterways near Phnom Penh. Discounting the risks of eating anything found in those polluted waters, I don’t understand the payoff of eating tiny bits of clams. But there’s obviously an attraction for them. Notice this woman’s mussel cart has three different varieties of tiny clams for sale.
