Why Is My Arugula Pesto Bitter?
Arugula Pesto can be bitter because arugula itself has a slightly bitter taste. Bitterness in arugula varies among different varieties of plants and how mature the plant is. Also, arugula pesto, if not made correctly, can have too much garlic or cheese, which intensifies the bitterness of the arugula. Developing new flavors by experimenting with the ingredients can help reduce the bitterness of arugula pesto.
