Three cheers and an amen for this new souply creation of mine. Swear to god I'm already looking forward to eating more and making it again. It came about as I attempted to warm my cold self, clean out my fridge, and feel truly sated, and I must say it's a huge success on all counts! Literally chock full of leeks, onions and sunchokes, those flavors are buttressed by roasted garlic, thyme, nutmeg, pecorino and buttermilk. I cooked everything relatively slowly, in roughly three layers, and immersion blended at the end for a smooth yet still slightly textured mouth-feel. Some roasted and chopped chestnuts topped off my bowl, but these are optional so don't fret if you want no part of them.
I truly can't imagine a better meal on a cold night. Off to write up the recipe so as not to forget a thing. It'll be in Soups as Leeky Sunchoke Bisque.
