Why it works: Lamb and pork match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 623 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
Ragout of Mutton
Ingredients
Directions
Prepare the meat
Fry the onion in plenty of dripping until golden.
Add the mutton and fry for 5 minutes.
Parboil the sweetbreads, then cool in cold water, wipe, slice, and fry in the fat.
Stew
Layer the sliced pork in a saucepan, followed by the mutton, sweetbreads, onion, and green peas.
Season with pepper and coarse sea salt, then cover with gravy.
Cover with a tight lid and stew gently for 1 hour after boiling.
Thicken and finish
Remove the meat and sweetbreads, thicken the gravy with browned flour.
Pour the thickened gravy over 2 beaten eggs, stir for 1 minute over heat, and then pour over the meat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Forms the main body of the ragout and becomes tender during slow stewing.
- Eggs
- Thicken the gravy slightly and add richness when stirred over heat.
- Browned flour
- Thickens the gravy so it coats the meat rather than running off.
- Streaked salt pork
- Adds fat and savoury flavour that carries into the stewing liquid.
- Lamb sweetbreads
- Contribute a soft, creamy texture and a delicate richness to the dish.
The step that matters
Stirring the egg into the hot gravy. If the gravy is too hot or stirred too little, the beaten egg can scramble into small curds instead of smoothly enriching the sauce. Stir steadily over gentle heat so the egg thickens evenly.
