  1. Meat drippings or butter – The source of smoky flavor.

  3. Lemon juice – A tangy note to bring everything together.

  4. Leeks – The star of the show, make sure to clean them well and slice them up before roughly chopping.

  5. Garlic – A must-have in any savory dish, use either fresh cloves or pre-made paste.

  6. Flour – To thicken up the sauce.

  7. Chicken stock or broth – Adding richness and depth of flavor.

  8. Milk – For a creamy and comforting touch.

  9. Ground Mustard – A little goes a long way in adding pungent mustard flavor.

  10. Sour cream – To add tang and creaminess.

  11. Fresh tarragon leaves – To give it a fresh, almost minty flavor.


  1. First things first, let’s heat up that large frying pan over medium heat. If you’re using meat drippings, great, toss ’em in there. But if not, no worries, just melt 2 tablespoons of butter.
  2. Next, it’s time to add in those leeks. Make sure to move them around so they don’t burn and get nice and tender. While they’re cooking, go ahead and add in some chopped garlic or garlic paste.
  3. Once the leeks are nice and soft, it’s time to add in the flour and start whisking in the chicken stock and milk. Let it simmer and thicken for about 15 minutes, stirring occasionally. If you have some protein, feel free to toss it in there too.
  4. Once it’s thickened, add in the ground mustard and sour cream. Squeeze in some lemon juice, season with salt and pepper and toss in some fresh tarragon leaves.
