Green Goddess Dressing
In a food processor, pulse the egg yolk with the lemon juice for 1 minute. With the engine running, slowly drizzle in the remaining 1/2 cup of grapeseed oil in a thin stream until emulsified. With the engine still running, add the herb puree, blending until smooth and emulsified. Season the dressing to taste with salt and pepper and, if necessary, more lemon juice.
