One of days, I found myself that I am so preoccupied with thoughts of white truffle oil after seeing the piece of paper that contained recipe for wild mushroom soup with white truffle foam in my cookbook. I remembered how it was made of and how it tasted. I was very amazed how it tasted along with white truffle foam--one of best soups I ever tasted and gobbled a bowlful of soup. It is darn good. The foam are made of heavy cream and white truffle oil. Heat first, not bring to boil. Add the oil and blended with immersed blender until the foam started to float. Scoop the foam from blender, drizzle over mushroom soup. Viola! Wild mushroom soup with white truffle foam.
I am sure that some of you are not familiar with interesting White truffle oil. It is not a cooking oil, it is a flavoring oil to enhance the dishes by drizzling over the food. I had hard time to explain how it tasted. Some sources that I read, said, "earthy and mushroom flavor" I don't agree with that and this "flavor". Its flavor changed when you tasted it and gave me nice aftertastes unlike any mushrooms I knew of. I already tasted real white truffles that I used it for cooking--Scalloped potatoes with white truffle, drizzled with white truffle oil. It smell like strong scent of wild mushroom that was smothered by earthy scent. I did not say the flavor, I said, the scents that enhanced my tongue and gave me more to eat the delicate food that blended into with earthy scent with nice flavors of meats, or potatoes, or anything come from the roots. In my opinion, the oil work best with anything that come from the roots like potatoes, carrots, and other any bland food that need some improvements. And with wild game meats, too.
I think I should show you the picture of white truffle look like:

White Truffle Risotto
Salt and White Pepper, to taste
2 ounces , White Truffle Oil
4 1/2 ounces , Fresh Parmesan Cheese Grated
4 ounces , Butter
1 small , Yellow Onion Minced
6 cup(s) , Chicken Stock
2 cup(s) , Arborio Rice
2 ounces , Italian white Truffle
(I don't know how anyone can afford the 2 ounces of Truffles. It doesn't matter me where it come from. I received white truffles from the locals also, even bought few from farmers Market if they are available. Pretty cheap than get it from Italy. It is very beautiful gems in area of Oregon forest. I knew it costs more than the mushrooms used to be, due to how hard to find the truffles in remote area--most of mushroom hunters won't reveal their sources where they find. I respect their business, If I knew where, still I won't reveal where it is, I am serious. Its cost depends on the season, if very small numbers of truffle, mean more cost. More demands, more costs. I was told that last season is not good for truffles, more money.)Instructions :
Remove any dirt or soil from the truffle very carefully with a mushroom brush. Do not wash as the truffle should be kept dry and not get mushy.
In heavy bottom stainless pot, sauté the onion with about 2 1/2 ounces butter, cook until translucent. Add the Aborio rice, mix thoroughly and cook about one minute over moderate flame. Add 2 cups of the chicken broth and stir almost constantly.
As the rice absorbs the liquid, keep adding it in 1 cup increments until almost fully absorbed, this process should take between 18-20 minutes. Add remaining butter and the cheese (start with 4 oz. then add remaining if necessary). Add the truffle oil - you should now adjust your seasoning with fresh white pepper and kosher salt (taste the risotto before you season - you might not need any salt).
Place the risotto into 4-6 bowls - it should have a creamy texture.
Slice truffles (use a truffle slicer) onto each bowl of risotto and serve immediately.
