nut umami

In a can of mixed nuts, it is only the pecans that possess a peculiar earthy flavor that is the essence of pure nuttiness. That essence, that is even more pronounced in the hickory nut, is that under-flavor that is nut umami, which can also be measured in intensity. Walnuts, especially black walnuts, have a more bitter drying flavor, that is at the bitter end of the nut umami spectrum, whereas the pecan and hickory are in the balanced and more centered warm spot on the nut umami scale.

Those roasted pecans exude the most wonderful nut umami.
