How to make broth for risotto

If rice is 70% of risotto, broth is 25%. Just a few percent left for butter, cheese and the main ingredient. Yet almost everyone — even experienced cooks — uses bouillon cubes or, worse, water. The result is a flat dish: no depth, no third dimension.

A good broth is the difference between "I made a risotto" and "I made the risotto." It costs two hours of passive cooking and gives you three months of frozen broth. No excuse.

Why broth matters so much

During cooking, rice absorbs broth ladle by ladle. Everything in the broth ends up concentrated in the grain. If the broth tastes of chicken, smells of herbs and has a sweet root note, all of that multiplies on the plate.

By contrast, bouillon cubes give you monosodium glutamate, salt and little else. You feel it immediately on the palate as an artificial, dry note.

Beef broth (the classic for most risottos)

Works for: meat risottos, cheese, Milanese, truffle, Barolo. Practically all northern Italian risottos.

Ingredients for 2 litres

• 500g beef shin (with bone if possible)
• 500g old hen (or whole chicken)
• 1 marrow bone (optional, adds richness)
• 2 carrots, 1 white onion with the skin on, 2 celery stalks
• 2 cloves, a few black peppercorns
• 1 bay leaf, parsley stems
• 3 litres cold water, coarse salt

Method

1. Put the meat in a pot with cold water (not boiling: cold extracts flavour). Bring slowly to a boil.
2. Skim the surface with a small ladle: the grey foam is coagulated proteins — remove for a clear broth.
3. Add whole vegetables (onion with skin gives golden colour) and aromatics.
4. Simmer on very low heat, uncovered, for 3 hours. Never hard-boil: the broth clouds.
5. Strain through a fine sieve or cheesecloth. De-fat as much as possible (easier after a night in the fridge).

Vegetable broth

Works for: vegetable risottos, delicate cheese risottos, vegetarian, herb-based.

Ingredients for 2 litres

• 2 carrots, 2 celery stalks (with leaves!), 1 white onion, 1 leek
• 1 ripe tomato (for colour)
• 4 parsley stems, 1 bay leaf, 1 thyme sprig
• 2 black peppercorns, coarse salt
• 2.5 litres cold water

Method

1. Wash the vegetables (onion with skin for colour) and roughly chop.
2. Put everything in a pot with cold water.
3. Bring to a boil, lower to minimum and simmer uncovered for 45 minutes. Never longer: beyond, vegetables release bitter notes.
4. Strain and salt lightly.

Fish stock (fumetto)

Fumetto is the fast broth of sea cuisine. Done in 20 minutes — longer would ruin the flavour with bitter notes.

Ingredients for 1.5 litres

• 1 kg white fish heads and frames (sea bream, bass, gurnard). Avoid oily fish: too intense
• 1 onion, 1 carrot, 1 celery stalk, 1 bay leaf
• 1 lemon halved
• ½ glass dry white wine
• 1.8 litres cold water, salt, peppercorns

Method

1. Rinse heads and bones well, removing gills (they make it bitter).
2. In a tall pot, heat a little oil and lightly brown the roughly chopped vegetables.
3. Add fish, wine and let evaporate 2 minutes.
4. Pour in cold water, bay, lemon and pepper.
5. Bring to a boil, skim and simmer on very low heat for exactly 20 minutes.
6. Strain through cheesecloth for a clear stock.

Dried mushroom broth

It's more an "essence" than a broth. Use it together with vegetable broth to add umami and earthy depth. Indispensable in mushroom risottos.

Method

1. 30g dried porcini in 400ml warm water (not boiling: would kill the aromas).
2. Soak for 30 minutes.
3. Strain through a sieve lined with cheesecloth (dried porcini always carry a little sand).
4. Add to vegetable broth midway through the risotto cooking — not at the start, to keep aromas fresh.

What temperature to add broth to risotto

Simmering, around 90°C. Never at a full boil (it clouds and splashes), never cold (stops the cooking).

Keep the broth on a burner next to the risotto pan, on the lowest flame. Stir occasionally to prevent a skin from forming.

How to store broth

Method	Duration	Notes
Refrigerator	3-4 days	De-fatted. Covered. Re-boil before use.
Freezer (ice cube trays)	3 months	Very handy: defrost 6-8 cubes at a time.
Freezer (zip bags)	3 months	Label with date and type.
Sterilized vacuum jars	6 months	Professional technique, needs pressure cooker.

Common broth mistakes

1. Bouillon cubes: glutamate covers natural flavours. If you must, choose organic without added MSG — but it'll never match homemade.
2. Cooking at full boil: broth clouds. Always at a simmer.
3. Not skimming: broth stays fatty and heavy.
4. Salting at the start: water evaporates over 3 hours and concentrates. Salt at the end, gradually.
5. Using tired vegetables: old, slimy scraps make a bitter broth.
6. Using red onion: too sugary, unbalances.
7. Adding garlic: in a risotto broth it ruins the clarity. Add garlic in the pan, not the broth.
