Toast the walnuts in a dry pan for about 1 minute (see notes in blog post)
Remove stalk from rosemary and chop roughly
Put all ingredients into food processor and blitze till you get a sauce. Add more oil if you want it runnier.
Season with salt and pepper to taste.
Allow to chill in the fridge for 30 minutes to let those flavours develop.

Notes
A really rich and aromatic pesto perfect on crostini with roasted tomatoes as well as in the usual pasta etc.This will keep for up to 2 weeks in the fridge in a covered jar, top unused pesto with olive oil to stop it disscolouring.
