I went upstate NY and bought two very large batches of arugula from a small farm. I knew if I didn't make it right away they would go bad. So I decided to make a pesto sauce. This gluten free lemon pesto was very flavorful. I changed the nuts and used almonds instead of the traditional pine nuts and I was pretty impressed with the results.
I never used to like the taste of arugula, I thought it was too bitter. Now I love the peppery, nutty flavor that the arugula imparts. Maybe I had a bad batch because if the leaves are allowed to mature too long the plant will become very bitter. Also, there is a difference between mature arugula and baby arugula. The baby arugula that you buy in the supermarket is definitely milder.
So this is what the mature arugula looks like. As you can see the leaves are larger than the baby arugula. The flavor is stronger so I blanched these to soften make it a little milder. You can use this pesto sauce on almost anything!
