Important: Safety Warning
This recipe calls for animal brains or related nervous-system tissue. Cattle brain and spinal tissue can transmit bovine spongiform encephalopathy (BSE), the cause of variant Creutzfeldt-Jakob disease in humans, which is fatal and has no treatment.

Croquettes of Calf's Brains
Boil one-half pound of brains gently for about twenty minutes, and then put them in cold water for a few minutes; peel off the outside, chop up the brains and add one-half breakfast cupful of breadcrumbs; mash all together, add a teaspoonful of finely-minced parsley, one ounce of butter, the yolk of an egg, a little lemon juice, grated nutmeg, and salt and pepper to taste. Mix all well together, and after flouring the hands make it up into shapes resembling sausages. Coat these with flour and fry in a wire basket, in lard or butter, until they are of a slight yellow color. Serve with cream sauce.
The technique here is sound late-Victorian hotel cookery, but the main ingredient is the problem: bovine brain is now classed as specified risk material in most of the world, and no cooking step in this recipe addresses that.
- Why brain is restrictedBrain and spinal cord are the tissues that carry the highest infectious load in bovine spongiform encephalopathy. Following the BSE epidemic of the 1980s and 1990s, regulators in the UK, the EU and the United States removed central nervous tissue from cattle from the human food supply, either entirely or above a set age at slaughter.
- Cooking does not helpThe infectious agent is a misfolded protein, not a bacterium. Twenty minutes of gentle boiling and a turn in the fryer destroy ordinary pathogens but leave prions essentially intact; normal kitchen heat is far below the range that degrades them.
- SourcingCalf's brains as Oscar knew them — bought loose from the butcher, no age documentation, no inspection record — are hard to come by now. Brain from young cattle is still sold legally in some jurisdictions, but under specific regulatory conditions, and the casual purchase this recipe assumes is largely gone.
- If you want the dishUse a current, regulated recipe from a source that addresses the sourcing question. Do not adapt this one.
- For reading, not cooking: the unitsA "breakfast cupful" is the large breakfast cup of the period, roughly 8 to 10 fluid ounces — the original is genuinely imprecise here. One ounce of butter is two tablespoons.
- For reading, not cooking: the frying"Fry in a wire basket" means deep frying in a basket lowered into fat, a standard hotel method. "A slight yellow color" is a much paler finish than a modern cook would take a croquette to, and reflects the fact that the brains had already been boiled.
Oscar Tschirky ran the dining rooms of the Waldorf, and his 1896 book records what a very large American hotel kitchen actually turned out, including a long roster of variety meats. Calf's brains — cervelle de veau in the French kitchen the Waldorf modelled itself on — were prized for a texture nothing else supplies: soft, almost custardy, and traditionally handled by poaching, cooling, peeling the membrane and then either crumbing and frying or serving in black butter. Turning them into croquettes bound with breadcrumbs and egg yolk was the standard hotel solution for a delicate, perishable ingredient, and the cream sauce and grated nutmeg place the dish squarely in the Anglo-French repertoire of the 1890s. Brains stayed common on American menus into the mid-twentieth century; BSE regulation, rather than any change in taste, is what finally removed the bovine version from general sale — in the United States the specified risk material rules followed the December 2003 BSE case and took effect in 2004.
