A question about a recipe: Thomas Keller's Butternut Soup with Brown Butter, Sage, and Nutmeg Crème Fraîche

I have a question about the recipe "Thomas Keller's Butternut Soup with Brown Butter, Sage, and Nutmeg Crème Fraîche" from Genius Recipes. How would one make the best vegetable stock for this soup? I'm putting this on the menu for a special dinner coming up. Thank you. ;o)

I am SO glad you asked this question. I made this soup last week, and I kept thinking that a Keller soup recipe really required a more Keller-worthy broth than what I threw together.

The Cook's Illustrated article drbabs mentioned is interesting. It recommends celery root (mild yet complex), leeks (low sugar, neutral), freeze-dried onion (for depth--but how Cooks Illustrated!), tomato paste (savory depth without identifying as a tomato). They suggest no celery (bitter and sour), onions (sulfurous and sweet), tomatoes (mild and watery), sun-dried tomatos (sweet-sour). They also add soy sauce (umami, and it worked better than shiitake mushrooms or kombu). I'm not sure whether to give it a go or not. But I'm looking forward to hearing what you decide.

This month's Cooks Illustrated has a recipe for vegetable broth that I think would work fine. Do you get the magazine? Here's a link to the recipe: http://www.cooksillustrated.com/recipes/8204-vegetable-broth-base?incode=MCSCZ00L0

If you can't open it, message me privately and I'll send it to you.

I love sweating onions until sweet, adding the usual carrot and celery AND the guts from any winter squash. It makes a beautiful and tasty golden broth.

Butternut seems to work the best. I made acorn squash dog biscuits this morning and my small acorn squash had mostly seeds and the strings were very pale.

HLA, I like the idea of mushroom stock. Is that recipe available only in the book?

AJ - I really like the mushroom stock recipe from Fields of Greens. It's rich and not too sweet, so I think it will work well for a butternut soup. http://www.epicurious.com/recipes/food/views/Mushroom-Stock-15319
