Tuber gibbosum
A tier
Tuber gibbosum is the Oregon spring white truffle, fruiting later than oregonense and carrying its own garlic-spice profile under Northwest conifers. Morphologically distinct to specialists, it enters kitchens as another regional white that rewards careful cleaning and raw shaving. Aroma is robust; size is still modest compared with Italian magnatum. Spring menus can feature gibbosum when autumn-winter oregonense has faded. Pair with asparagus, soft cheese, and early herbs rather than heavy game. As with all whites, heat is the enemy of the top notes.
