So I have a nice big bunch of basil and I'd like to make pesto. I have pine nuts. I admittedly only have the parm that comes in a jar for sprinkling but I'd like to make do. I have grape seed oil. I'd like to make pesto but whenever I've tried in the past it comes out as this thick leafy mash or just some soupy thing with green bits which lack the body one normally sees in pesto. I don't have a food processor. Closest I've got is one of those chopper attachments for my immersion blender. Any pesto making tips for me or lower calorie and easier to make alternatives?
