I made pesto for the first time on Saturday using the Rouxbe recipe. I served it with some local fresh pasta and it was awesome.
However, sometime on Sunday or Monday I started noticing a strange bitter aftertaste when eating other foods. At first I chalked it up to whatever I was eating or drinking at the time, but it kept happening with different things. (especially sweeter tasting things)
Yesterday it was bugging me so I did some searching on google and was surprised to discover that this problem has been associated recently with pine nuts. Has anybody else encountered this?
