Lao Gan Ma is some of the most delicious stuff to come out of China. It's crispy, it's a little smokey, it's spicy, it's oily, it's good on almost everything.
But, you can't pay these prices for it. Find a local Asian grocery and you can get it for $3-4 a jar. Only if you live out in the boondocks should you pay as much as these online dealers want.
