Tonight I'm making pesto...from scratch...my mouth is salivating...but I am not without apprehension. Apprehension? Over pesto? Let me explain...... several years ago after a delish meal of homemade pesto, I slipped into my PJ's, squeezed some toothpaste onto my brush and had the oddest experience. The toothpaste didn't taste like toothpaste at all, instead, there was an overwhelming taste of bitterness I came downstairs and asked Marco and the girls to try the toothpaste.. does it taste weird to you? nope, all fine.... so strange, I thought and took myself off to bed... Over the next week things got worse EVERY single thing I ate had the same taste..bitter, bitter, bitter! apples, yoghurt, salad. chocolate, chicken, everything bitter! No differentiation whatsoever between foods.... It was like all of the different areas of my taste buds had been switched off and turned to bitter sensors, sweetness, salty, sour, umami, all gone bitt...
