Pesto is very simple and there is no need to measure. Pesto can be made so many ways, pretty much any nuts or seeds will work. I buy organic pine nuts from Costco and I leave them in my freezer, up to 6 months. I use half basil leaves and I grow my own. For the other half, I use any greens I have in the fridge, such as spinach or kale. This time I used something out of my front yard. Why not? Dandelions are usually easy to find except this year. On the weekend I found lots at camp. The babier the better! The baby leaves are less bitter and spring is the perfect time for harvest. I kept mine in a plastic container, or wrap the leaves in paper towel and refrigerate.
Just want to clear any confusion. Handful of pine nuts is 1/2 cup and 3 handfuls of basil and greens is 1 cup. Enjoy! My kids don’t love pesto but they eat it. I love it so I’m happy! Have fun foraging!
