I bought some fresh summer truffles at Comptoir Gascon in London. Dark brown on the outside and white on the inside. Whilst they smelt good in the shop - fairly subtle but distincly truffle, I was disappointed when I used them in a dish, I found them nutty in texture and taste - very little to no truffle flavour or aroma. I had no experience of buying or using them before, so I may not have chosen well. However afterwards I had a pigeon dish using Summer Truffles at a well regarded restaurant in France. Whilst the dish was very good, the summer truffles tasted very similar to those I had bought in London, again very little/no truffle taste. If this is not a common experience with summer truffles please advise, help on selecting truffles would also be appreciated.
