Mousseline is a very fine, delicate forcemeat made by processing fish, shellfish or poultry with ingredients such as egg white and cream. The mixture is passed through a fine sieve to create a smooth texture, then cooked gently. It is used for quenelles, terrines, stuffings and other refined preparations.
Use lean, suitable raw material and keep the ingredients, bowl and blade cold during processing. Process the protein with the specified binder and seasonings, then incorporate cold cream gradually. Excessive friction or heat can damage the protein structure and cause the mixture to split or become greasy. Pass the mixture through a fine tamis or sieve when a particularly smooth texture is required.
Cook a small test portion before shaping the full batch. This allows the cook to check seasoning, firmness and emulsion stability. Shape the mousseline into quenelles, pipe it into moulds or use it as a filling, then cook gently by poaching, steaming or another controlled method appropriate to the recipe.
Example: a fish mousseline can be shaped into quenelles and poached gently in a court-bouillon, then served with a light sauce.
Forcemeat is the broader category of seasoned ground or processed mixtures. Mousseline describes a particularly fine, light and often cream-enriched style. It is not simply any smooth purée.
Food-safety note: keep raw fish or poultry mixtures refrigerated during preparation, prevent cross-contamination and cook using the applicable validated food-safety process.
