There is a rumour that white truffles harvested in Europe by pigs or dogs are much better in terms of flavour than those from North America, hence the reason for the higher price of European white truffles, the main reason given for the aroma difference is that it has something to do with the way the Americans harvest their truffles.
Are European white truffles much more aromatic and flavourful than the North American ones? I would like to try truffles but I do not want to spend too much money on the European ones if the American ones are just as good or nearly as good.
