Probably the best thing I made and ate last year was this white truffle risotto (recipe from the French Laundry cookbook). It's a simple dish and it really is good. I got the white truffles from Market Hall. Folding in whipped cream, the white wine, the amount of butter, the small amount of Parmigiano-Reggiano, and onions versus shallots, surprised me when I was making it. I think I made risotto correctly for the first time — I used fewer ingredients and paid more attention to actual cooking with some toasting and a lot of absorbing and stirring that needs to happen to maintain the integrity of the rice.
The second decadent thing we ate recently was this Hokkaido snow beef from Chateau Uenae. "Hokkaido Snow Beef. Located in the Hokkaido Prefecture, about an hour outside of Sapporo is Chateau Uenae. Cattle is raised in sub zero temperatures in the pristine Hokkaido countryside."
It's an A5 BMS 11 wagyu that's over the top. The superlatives of rich, fatty, melt in your mouth I heard about are all pretty true. The fat coats your tongue but it's a delicious fat. I got these 4 ounce steaks from A-Five Meats which is close to our office near the Bay Bridge in San Francisco. This is supposed to be a "holy grail" type of steak and it is good and I would certainly buy and make it again.
