This sauce is so ridiculously good. The leeks give it a nice mellow, sweet taste that combines nicely with the smokiness of the paprika. The strong oregano flavor just ties everything together and makes it extra delicious. I think I will put this sauce on my next pizza, yum!
Oh and you really want to use an immersion blender here, as the sauce is quite thick - a regular blender will work but you will have to scrape it down every 2 seconds and it will take forever.
