Finnan Haddie and Leek Sauce


  • (serves 4)
  • 1 lb Finnan Haddie.
  • 2 3/4 cups of milk.
  • 2-oz butter.
  • 1 1/2 tbs plain flour.
  • 1/2 tsp turmeric.
  • 1 tsp Coleman’s English mustard powder.
  • 1 tsp ground black pepper.
  • 1 very small pinch cayenne pepper.
  • 1 medium leeks diced.


  1. Keep the haddock filets in the large chunks with the skin on. Cover with the milk in a pan and bring up to a gentle simmer for four minutes. Remove pan from heat and let it sit another two minutes — Six minutes total — Pour milk into a jug.
  2. After cooling, remove haddock from skin, keep in large flakes. Make a white sauce with the flour, 1-oz butter and smoky flavored milk. Keep a third of the milk back.
  3. Add turmeric, English mustard powder, small pinch chili powder (just enough to ‘pick up’ the flavor but not enough to add heat) & pepper.
  4. Sauté leek in 1-oz butter & add to the sauce. Add the haddock flakes including any juice that has accumulated. Stir, bringing up heat. Thin a little with remaining milk to desired thickness. Gently heat to serve.
