How to Make Perfect Stock from Scratch: Chicken, Beef and Vegetable

Stock is an extraction. You are using water, heat and time to pull three categories of compounds from bones, vegetables and aromatics:

**Gelatin** — collagen in connective tissue and bones breaks down into gelatin with prolonged cooking (2–6 hours at a gentle simmer). Gelatin gives stock its body and that characteristic 'wobble' when cold. A good chicken stock should set to a loose jelly in the fridge. A good veal stock should set almost solid.

**Flavour compounds** — aromatic volatile compounds from vegetables and herbs, plus glutamates (natural MSG) from browned meat and bones, create the stock's flavour profile. This is why roasting bones before simmering produces dramatically richer colour and taste — the Maillard reaction creates hundreds of new flavour compounds.

**Minerals and nutrients** — calcium, magnesium, phosphorus from bones leach into the liquid, along with vitamins from vegetables.

The enemy of great stock is vigorous boiling. A rolling boil emulsifies fats into the liquid (making it cloudy and greasy) and can cause proteins to form a grey foam that clouds the stock. The goal is a gentle, barely-perceptible simmer — you should see the occasional lazy bubble rising to the surface, not a turbulent roil.

**Ingredients (makes ~2 litres):** • 1.5–2 kg chicken carcasses, wings or drumsticks (or a mix) • 1 large onion, roughly chopped • 2 medium carrots, roughly chopped • 3 celery stalks, roughly chopped • 1 head of garlic, halved horizontally • 2 bay leaves, 10 peppercorns, small bunch of thyme and parsley stalks • Cold water to cover (about 3 litres)

**Method:** 1. **Blanch the bones** (optional but recommended for a clear stock): place raw bones in a large pot, cover with cold water, bring to a boil. Drain and rinse the bones thoroughly — this removes blood and impurities that cause cloudiness. 2. **Add bones and vegetables** to the pot. Cover with cold water by about 5cm. Starting with cold water and bringing it up slowly helps proteins coagulate gradually, producing a clearer stock. 3. **Bring to a bare simmer** over medium heat. This should take 20–30 minutes. As it heats, skim any grey foam that rises to the surface. 4. **Reduce heat to very low.** The liquid should barely move. Partially cover. Simmer for **3–4 hours** for a light, delicate stock; **5–6 hours** for a richer, more gelatinous result. 5. **Strain through a fine-mesh sieve** (lined with muslin/cheesecloth for a crystal-clear result). Do not press the solids — this forces cloudy liquid through. 6. **Cool rapidly** in an ice bath, then refrigerate. Skim the solidified fat layer before use, or leave it as a protective seal.

**Roasted chicken stock:** Roast the bones at 220°C for 30–40 minutes until golden brown before proceeding. The Maillard reaction creates a dramatically deeper colour and flavour — this is a 'brown stock.'

Beef stock requires longer cooking and the flavour benefit of roasting is even more pronounced than with chicken.

**Ingredients (makes ~2 litres):** • 2 kg beef bones (knuckle, shank, marrow bones — ask your butcher) • 500g oxtail or beef shin (adds collagen and flavour) • 2 onions, halved (charred cut-side down in a dry pan is a classic technique) • 3 carrots, 4 celery stalks, 1 head garlic • 2 tbsp tomato paste • 250ml red wine • Bay leaves, thyme, peppercorns

**Method:** 1. Roast bones at 220°C for 45–60 minutes, turning halfway, until deep mahogany brown. Don't burn — bitterness is hard to fix. 2. Place roasted bones in a large stockpot. Pour off excess fat from the roasting tray; add a little water to the tray and scrape up the caramelised bits (fond) — add this to the pot. 3. Cook the tomato paste in a dry pan until it darkens slightly (pinçage) — this deepens colour and adds umami. Add the wine and reduce by half. 4. Add all vegetables, the wine reduction, herbs and cold water to cover. 5. Bring slowly to a simmer. Skim carefully. Cook on the lowest possible heat for **8–12 hours** (or overnight if using a very low oven at 90°C). 6. Strain, cool rapidly, degrease.

**Reduction to demi-glace:** Return strained stock to the pot and reduce by 75%. The result is demi-glace — a deeply concentrated, syrupy glaze used in small quantities to finish sauces. It freezes well in ice cube trays.

Vegetable stock cooks in just 45 minutes — any longer and many vegetables turn bitter. The key is selecting vegetables carefully:

**Good additions:** onion, carrot, celery, leek, fennel, mushrooms (add incredible umami depth), tomato, garlic, corn cobs, parsley stalks, bay, thyme

**Avoid:** cruciferous vegetables (broccoli, cabbage, cauliflower), beets (turn it purple and earthy), starchy potatoes (make it cloudy and thick), artichokes (add bitterness)

**Method:** Sweat the vegetables in a little oil first — this step, often skipped, makes a noticeable difference by creating fond and caramelisation that adds colour and depth. Add cold water, bring to a simmer, cook for exactly 35–45 minutes. Strain immediately.

**Mushroom stock:** A subset worth knowing. Dried porcini or shiitake mushrooms (rehydrated and added with their soaking liquid) create an incredibly rich, umami-dense stock with glutamate levels rivalling meat-based stocks. Excellent base for risotto, ramen broth and vegetarian gravies.

**Refrigerator:** Stock keeps for up to 5 days in the fridge. The solidified fat layer that forms on top acts as a protective seal — leave it until you're ready to use the stock.

**Freezer:** Stock freezes excellently for up to 6 months. Reduce it first (by 50%) to save freezer space, then reconstitute with an equal volume of water when using.

**Safety:** Cool stock rapidly using an ice bath and refrigerate within 2 hours of cooking. Never leave stock at room temperature for extended periods — the combination of protein, moisture and warm temperatures is ideal for bacterial growth.

**Seasoning:** Don't salt stock during cooking. Salt concentrates as stock reduces, and salted stock added to a reducing sauce can quickly become overseasoned. Season only at the point of use.

**Clarification:** For a crystal-clear consommé, use the classic raft method: mix lean minced meat, egg whites and mirepoix, stir into cold stock, bring to a simmer. The proteins coagulate and trap all particles, rising to the surface as a 'raft' that you then strain through.
