Why it works: Vinegar and mustard are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Baked Ham
Ingredients
Directions
The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Soak the ham in cold water.
Simmer gently for 2 to 3 hours to loosen the skin.
Remove the skin and place the ham in a roasting pan.
Mix the vinegar, hot water, and mustard.
Pour the mixture over the ham.
Glaze and bake
Bake at 300°F (150°C) for 2 hours.
Baste the ham with the liquid.
Cover the ham with brown sugar, pressing it down firmly.
Bake for an additional hour until the sugar forms a thick crust and the ham is golden brown.
Cool and press
Drain the ham and let it cool on a dish.
Once cool but not cold, press the ham with a flat dish and a weight on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Adds sweetness and caramelizes under heat to form a browned, thick crust.
- Vinegar
- Adds acidity that balances the sweetness of the sugar glaze.
- Mustard
- Adds sharp, savoury flavour to the glazing liquid.
- Hot water
- Forms the liquid that moistens the ham while it bakes in the pan.
The step that matters
Pressing the ham when cool but not cold. Pressing at this stage lets the warm, still-soft meat settle into a firm, even shape as it cools. Pressing fully cold ham is harder, and pressing it too warm can squeeze out juices and make it crumble.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
