The summer variety of the black truffle, these delicious mushrooms are subtle and mildly-flavored. Theyāre in season from May through August, and while they lack the intensity of the winter or fall types, they are a great way to add some nice truffle flavor to light summer and spring recipes – without breaking the bank. In shape and looks, they look the same as the winter variety, but youāll notice that they donāt have that intense aroma.
