Herb Jus

Ingredients

Equipment Needed

• •Roasting pan (used for the roast)
• •Wooden spoon for scraping fond
• •Fine-mesh strainer
• •Small saucepan
• •Whisk (if mounting with butter)

Instructions

1. 1

   Assess the fond

   Transfer your roast to a cutting board to rest. Look at what remains in the pan. You want those dark, caramelized bits stuck to the bottom, the fond. If there is excessive fat pooling, carefully pour most of it off, leaving about a tablespoon. Keep the brown bits. They are everything.

   If the fond has burned black rather than browned deeply, start fresh with just stock and shallots. Burned fond makes bitter jus.
2. 2

   Soften the shallot

   Set the roasting pan over medium heat on your stovetop. Add the minced shallot and cook, stirring, until it softens and turns translucent, about two minutes. The residual fat in the pan is enough. The shallot will pick up color from the fond as it cooks.

3. 3

   Deglaze with wine

   Pour in the wine. It will hiss and steam. Use a wooden spoon to scrape up every bit of fond from the bottom of the pan. Work the corners. The liquid should turn a deep amber as it absorbs everything the roast left behind. Let it reduce by half, about two minutes.

4. 4

   Add stock and herbs

   Pour in the stock. Add the thyme sprigs and rosemary sprig, pressing them into the liquid. Bring to a simmer, then reduce heat so the surface barely trembles. Let it cook for ten to twelve minutes, reducing by about one third. The jus should coat a spoon lightly but still flow freely.

5. 5

   Strain and finish

   Set a fine-mesh strainer over a small saucepan. Pour the jus through, pressing gently on the shallots and herbs to extract their flavor, then discard them. Return the saucepan to low heat.

   If your jus seems thin, let it simmer a few minutes longer. Reduction concentrates flavor naturally, no thickeners needed.
6. 6

   Mount with butter (optional)

   For a slightly richer, glossier jus, remove the pan from heat and whisk in the cold butter cubes one at a time. The butter will emulsify into the warm liquid, adding body and sheen. This step is optional. A jus without butter is cleaner, more austere, equally good.

7. 7

   Add fresh herbs and season

   Stir in the chopped parsley and snipped chives. Taste. Season with salt and pepper, remembering that the roast has its own seasoning. The jus should taste bright and clean, meaty but not heavy, with the herbs singing at the finish. Serve immediately.

Chef Tips

• •Match your stock to your roast. Chicken jus for poultry, beef stock for red meat. A jus made with mismatched stock tastes confused.
• •The herbs you choose should echo the herbs you roasted with. If your chicken had tarragon under the skin, finish the jus with tarragon. Let the conversation continue.
• •A jus cannot be rushed. Reducing concentrates flavor, but it takes the time it takes. Twenty minutes is not long to wait for something this good.
• •If you lack pan drippings, you can build a simple jus by browning meat trimmings or bones in a bit of oil, then proceeding with the deglazing. It will not have the depth of a true roast jus, but it will serve.
• •In winter, when fresh herbs grow sparse, look for greenhouse-grown thyme and rosemary at farmers markets. The best growers work year-round.

Advance Preparation

• •A jus is best made and served immediately, while the roast rests. It takes only twenty minutes.
• •If you must hold it, keep the jus warm over very low heat, covered, for up to thirty minutes. Add the fresh herbs just before serving so they stay vibrant.
• •Jus without butter can be refrigerated for two days. Reheat gently and add fresh herbs before serving.
