Flora's Wild Mushroom Soup
Bob Sargent is the chef at Flora, a restaurant in Arlington, Mass. He shares his recipe for wild mushroom soup below:
When I was in cooking school, I remember my instructor, Michel LeBorgne, telling us that when making a vegetable soup, we should use water as stock, to let the vegetable flavor come through. It wasn't what I expected from a French chef, since most recipes at that time called for chicken stock. The mirepoix, or seasoning vegetables used to flavor the water, provide the good flavor that I associate with so many savory dishes. The power of onions to make everything right is a true wonder! This recipe serves 8 to 10.
