Needs lots of adjustments. We tried it as per the recipe and it wasn't what we had hoped for. We made some additions - 1 T. butter, 1 c. cream, 1/4 t. mace and one more garlic clove. That was better but still not what we wanted. Seems to need less leek and more potato and use half-and-half instead of veggie stock. That would mean cooking the potatoes in a different pan and adding them already cooked. Use mace or nutmeg instead of rosemary. Would probably be better if half of the leeks and potatoes were pureed after cooking to thicken the brew.
