Allium Bisque with Frizzled Leeks & Rosemary

April 18, 2012

Test Kitchen-Approved

Author Notes: Simple, nourishing and fresh, this allium bisque combines the over-wintered onions, shallots and garlic with spring's leeks and fresh rosemary. The flavor is complex while it's mild sweetness is cut with a splash of white wine vinegar. Leeks caramelized in a bit of clarified butter deepen the soup's flavor, aroma and texture.Jenny McGruther

Food52 Review: The bisque is very accessible in terms of ease of preparation and availability and cost of ingredients. It was creamy and velvety without the addition of heavy cream, a major plus in my book. It tasted slightly sweet, and the frizzled leeks added a burst of intensity to what would otherwise be a fairly simple soup. However, the recipe doesn’t outline when and how to use the garlic, and the rosemary contributes very little flavor and was almost undetectable. This is a satisfying soup that successfully highlights the flavors of early spring alliums.Meg Salvia
