Urbani White Truffle Oil is the best I've found, but Boscovivo White Truffle Flavored Olive Oil is much less expensive and does an adequate job when preparing red meats or some heavy sauces. I have tried many, and my favorite, bar none, is Aceto Balsamico Di Modena Fini. I have been able to find it only at Williams Sonoma. Of course Digital Chef offers many nice vinegars, too, but not the Fini. Spices Spices drove Marco Polo and the European Age of Discovery.
Spices are the key to most recipes.
Irina and I have been experimenting with saffron lately which has, at times, been worth its weight in gold. Fresh oregano and basil are almost a requirement in continental cooking, but most of us do with dried spices. The key to many great recipes is stock. But we don't always have the time to take the 12 or 15 hours it takes to make a good one. Well, we have found the answer.
