- 120 g Unsalted Butter (softened to room temperature)
- 1.2 kg Whole Chicken (about 4‑5 lb, cleaned, trussed if possible)
- 3 L Chicken Stock (homemade or low‑sodium store‑bought)
- 200 ml Heavy Cream (cold)
- 2 Carrots (peeled, cut into 2‑inch pieces)
- 2 Celery Stalks (cut into 2‑inch pieces)

- 1 Onion (medium, quartered)
- 2 tsp Coarse Sea Salt (for seasoning the stock)
- 1 tsp Black Pepper (freshly ground)
Instructions
Prepare Watercress Butter
Remove stems from watercress leaves, wash the leaves in cold water twice, then pat completely dry with a clean kitchen towel.
Time: PT5M
Process Watercress
Place the dried watercress leaves in the food processor with the small blade attachment. Pulse for 30 seconds, scrape down, then pulse another 30 seconds until a wet paste forms.
Time: PT2M
Emulsify Butter
Add the softened butter to the watercress paste in three portions, mixing after each addition until a smooth, pale green compound butter forms.
Time: PT5M
Shape and Chill Butter Log
Transfer the butter onto a sheet of parchment, roll it into a rough log (about 5 cm diameter), wrap tightly in plastic wrap, and refrigerate for at least 15 minutes (or freeze for 5 minutes if in a hurry).
Time: PT15M
Prepare Vegetables and Aromatics
Peel and cut carrots, celery, and potatoes (if using). Slice leek (white part only) and quarter the onion. Set aside.
Time: PT10M
Bring Stock to a Boil
In the large saucepan, bring 3 L of chicken stock to a rolling boil over high heat. Add 2 tsp coarse sea salt and 1 tsp black pepper.
Time: PT5M
Add Aromatics and Chicken
Add the sliced leek, quartered onion, and a handful of extra leek pieces to the boiling stock. Carefully lower the whole chicken into the pot (remove a little stock first to avoid overflow).
Time: PT3M
Simmer Chicken
Reduce heat to maintain a gentle simmer. Add carrots and celery pieces. Partially cover the pan and simmer for 40 minutes, or until the internal temperature of the thickest part reaches 74 °C.
Time: PT40M
Reserve Broth and Vegetables
Using a slotted spoon, remove the chicken and set it on a warm plate, keeping the lid on the pot. Transfer the cooked vegetables to a separate pan with a splash of broth to keep warm. Skim the broth, discard the aromatics, and measure 300‑350 ml of the clear broth for the sauce.
Time: PT5M
Reduce Broth
Strain the reserved broth through a fine mesh sieve (or cheesecloth) into a clean saucepan. Bring to high heat and reduce by one‑third, about 100‑120 ml remaining.
Time: PT5M
Add Cream and Reduce
Stir in the cold heavy cream and continue to simmer, reducing the mixture by half until it reaches a semi‑syrupy consistency.
Time: PT3M
Incorporate Watercress Butter
Remove the pan from heat. Cut 60 g of the chilled watercress butter into small cubes. Whisk the butter into the hot sauce a few pieces at a time until fully emulsified. Finish with the remaining butter, stirring gently; the sauce should coat the back of a spoon.
Time: PT5M
Carve and Plate Chicken
Carve the poached chicken into breast slices or desired portions, removing excess skin if desired. Arrange on warmed plates, spoon over the watercress‑cream sauce, and surround with the reserved vegetables.
Time: PT5M
