It is a fact of life, that recipes from aristocratic families, tend to be low carb. They were formulated many many years before Ancel Keys and his low fat cherrypicked studies. They would use the best ingredients, often from their own estates. Beef, pork, lamb, wild game, freshwater fish, eggs, cream and butter.
The recipe itself, with measurements, can be found on Lady Carnarvon’s website.
