Heston Blumenthal at the Fat Duck has a pine thing going on at the moment. There is some discussion of it on this thread from page 5 onwards. It was a two part pre-dessert, first a little glass of Pine Sherbert Dib Dab which you sucked off a vanilla pod, then a Mango and Douglas Fir Purree, bavarois of lycee and mango, blackberry sorbet, beetroot and green peppercorn jelly. The pine flvour was pronounced in the first part in order to acclimatise the palate I was informed and highlight the subtle pine of the "main" dish. I know where Spencer is coming from on this, and maybe pine won't be taken up on a wide scale, but although I disliked the dib-dab, the second part was very successful.
