Why it works: Ketchup and sugar match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 260 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Sea Pie
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Assemble and bake
In a deep pie dish, layer the mutton chops, followed by the sliced apples and onions.
Sprinkle with herbs, salt, pepper, and sugar.
Cover the pie with suet crust and bake for 1 hour.
Finish the gravy
After baking, pour the gravy out from the side, cool it, skim off the fat, add the mushroom ketchup, and return it to the pie.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Neck mutton
- Provides the meat and rich juices that form the gravy in the pie.
- Onions
- Add savoury depth and sweetness as they soften during baking.
- Apples
- Add tart flavour and sweetness that balance the rich meat.
- Suet crust
- Forms a rich, tender pastry lid that seals in moisture and steams the filling.
- Mushroom ketchup
- Adds concentrated savoury, umami flavour to the finished gravy.
The step that matters
Skimming the gravy after baking. Mutton and suet release a lot of fat during baking. Cooling the gravy lets the fat rise and solidify so it can be skimmed off, leaving a cleaner, less greasy sauce before the mushroom ketchup is added and the gravy returned to the pie.
Swap the apple
How well each one fits the dish's main ingredients (onion, mutton, mushroom, ketchup, pepper, sugar):
- Lemonfits better
- Limefits better
- Red currantfits better
- Applethe original
Fit is the average pairing score against onion, mutton, mushroom, ketchup, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
