Frozen Oregon White Truffles
There are two species of white truffle found in the Pacific Northwest, commonly called Oregon white truffles. Tuber oregonense (winter white truffle) is the more prevalent of the two and has a similar appearance to the Italian white, with a smooth pale brown and reddish surface and a gleba of brown with white veins. It has a strong raw garlic and nutty cheese aroma, with hints of sweetness, cedar, cinnamon, and vanilla, with the classic truffle undertone of wet forest floor. The tuber gibbosum (spring white truffle) is similar to the Oregon winter white truffle, with a complex garlic and spice aroma, but the surface is brownish yellow with darker brown patches. Winter white is found October through March, and the spring white is found May through July.
