I wonder if there’s any consensus on what these might be. My personal votes would go to:
Apple Cider from Rainbow Orchards (Various farmer’s markets, $3-$7)
I haven’t willingly drunk apple juice since trying this.
Plain Pizza from Emilia’s (Berkeley, $20)
I can’t say I’ve stopped eating all pizza but Emilia’s since trying it, but I’ve certainly regretted most pizza since Emilia’s.
Almond Brittle from Paso (CJ Olsen’s Market in Sunnyvale, $5)
