tablespoons (1/4 cup)
small piece dried shiitake or porcini mushroom
1/4-1/2 inch in size*
dash of fish sauce
Add the mayo to a small bowl. Set aside.
In a spice grinder or mortar and pestle, grind up the dried mushrooms to a fine powder; enough to make 1/2 a teaspoon.
Add the mushroom powder to the mayo.
Add a dash of fish sauce.
Mix to combine.
*I normally have mushroom powder at the ready by grinding a decent amount at once and keeping it stored in an airtight container. This recipe calls for 1/2 a teaspoon of mushroom powder.
