Stocks & broths
shrimp stock
Fumet de crevettes · A delicate, highly flavored stock derived from the shells and heads of raw shrimp, used as a foundational broth in classical and modern seafood cookery. It provides a concentrated oceanic essence, subtle sweetness from aromatics, and a light gelatinous body that enriches sauces, soups, risottos, and rice dishes.
The formula
500 g raw shrimp shells : 1 L water
Aromatics ≈10 % of shell weight (≈50 g). For a stronger ‘fumet’, reduce the finished stock by half.
Identity
- Use raw shells only; pre‑cooked shells impart bitterness and off‑flavors.
- Simmered gently for 20–30 minutes; never boiled vigorously or extended beyond 45 minutes.
- Strained through a fine‑mesh sieve lined with cheesecloth to achieve a crystal‑clear broth.
- No added salt during preparation – seasoning is adjusted when the stock is used.
- Cooled rapidly in an ice bath and stored in airtight containers to prevent bacterial growth.
Ingredients
| Base | raw shrimp shells (heads optional) | Use fresh, raw shells; pre‑cooked shells will yield bitter, murky stock. |
| Liquid | water | Filtered or spring water for maximum clarity. |
| Aromatics | onion, roughly chopped | Provides sweetness and body; classic mirepoix base. |
| Aromatics | carrot | Adds subtle sweetness and color depth. |
| Aromatics | celery | Contributes herbal, slightly bitter notes. |
| Aromatics | bay leaf | Essential French bouquet garni component. |
| Aromatics | thyme | Imparts earthiness and complements seafood. |
| Seasoning | black peppercorns | Mild heat without overpowering the delicate shrimp flavor. |
Method
- 1Rinse the raw shrimp shells thoroughly under cold running water to remove ice, debris, and any residual blood.Removes impurities that would otherwise cause bitterness, cloudiness, or off‑odors in the finished stock.
- 2Combine shells, water, onion, carrot, celery, bay leaf, thyme, and peppercorns in a heavy‑bottomed stockpot.Begins the extraction of pigments, flavors, and gelatin from the shells while infusing aromatic support.
- 3Bring the mixture to a rapid boil over high heat, then immediately reduce to a gentle simmer.A quick boil extracts the shell’s color and proteins rapidly; lowering the heat prevents over‑extraction and keeps the broth clear.
- 4Skim the foam and any rising oil with a fine ladle during the first 5–10 minutes of simmering.Coagulated proteins and impurities rise to the surface; skimming ensures clarity and removes bitter compounds.
- 5Maintain a gentle, uncovered simmer for 20–30 minutes (never exceed 45 minutes).Prolonged cooking extracts iodine and chitin breakdown products that create harsh, bitter notes; a short simmer yields a clean, sweet broth.
- 6Strain the stock through a fine‑mesh sieve lined with cheesecloth, discarding the solids.Produces a crystal‑clear, impurity‑free liquid suitable for sauces and refined dishes.
- 7Cool the strained stock rapidly in an ice‑water bath to below 10 °C within 30 minutes, then transfer to airtight containers.Rapid cooling inhibits bacterial growth and preserves the fresh, delicate shrimp flavor.
Techniques that matter
Skimming
Removes coagulated proteins and fat, ensuring a clear, clean‑tasting stock.
Gentle simmer
Extracts flavor and gelatin without pulling bitter iodine from the shells.
Fine‑strain (cheesecloth)
Achieves a transparent broth essential for sauces and refined presentations.
Rapid cooling (ice bath)
Prevents bacterial proliferation and preserves the stock’s fresh aroma.

Substitutions
- crab shells → shrimp shells — Crab shells can be used interchangeably; they yield a slightly richer, sweeter stock with more gelatin.
- lobster shells → shrimp shells — Lobster shells produce a buttery, more robust broth, suitable for decadent bisques.
- fish stock → shrimp stock — Fish stock lacks the distinctive shrimp umami; it can serve as a neutral substitute in a pinch but will alter flavor profile.changes result
Troubleshooting
Stock tastes bitter or iodine‑like
Overcooked shells or use of pre‑cooked shells → Limit simmering to 20–30 minutes and always use raw shells.
Cloudy, murky appearance
Vigorous boiling or insufficient skimming → Maintain a gentle simmer and skim regularly during the first 10 minutes.
Muddy or off‑smelling stock
Stale shells or inadequate rinsing → Use fresh shells and rinse thoroughly under cold water before cooking.
Excessively salty
Added salt during preparation or use of salted aromatics → Omit added salt; season only when the stock is incorporated into a final dish.
