Leeks are warm in temperature, help to circulate Qi and Blood and eliminate Cold. Potatoes are neutral in temperature and nourish Qi and Yin. This is a generally nourishing soup, and by adding various other ingredients, can help to resolve a wide range of imbalances.
Yin deficiency: Unless you also have Dampness, fry the leeks in butter rather than oil and add some milk to the soup while reducing and/or a little cream at the end.
Yang deficiency: Add nutmeg while softening the potatoes, before adding the stock or add chopped rosemary while frying the leeks and garnish with rosemary to serve.
Blood deficiency: Use chicken stock rather than vegetable stock if you aren’t vegetarian.
Qi or Blood stagnation: Add ginger (while frying the leeks), nutmeg or turmeric (while softening the potatoes, before adding the stock) and be generous with the black pepper.
Damp or Phlegm: Gently fry an onion for a few minutes before adding the leeks, add chopped rosemary while frying the leeks and garnish with rosemary to serve.
5 medium leeks
8 small/medium potatoes
salt and pepper to taste
other ingredients depending on imbalance (see energetics)
Chop the leeks and fry gently in a little oil for around 5 minutes until soft but not browned. Slice the potatoes and add to the leeks and season.
At this point you may need to add more ingredients, depending on the energetics desired.
Pour or ladle over a small amount of stock and reduce. When the pan starts to get dry, add a little more stock and reduce again. Repeat until the potatoes are soft.
Pour into a blender (or use a stick blender) to create a smoother soup. Check seasoning and serve.
