Why it works: Tomato and capsicum match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 10,520 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Tomato Sauce
Ingredients
Directions
The book says “a cool oven”. The 300°F in the steps is the modern equivalent, not the book's own figure.
Prepare the tomatoes
Place the tomatoes in a jar and set it in a cool oven (300°F / 150°C) or on the hob until soft.
Peel the skins and remove the seeds.
Season and simmer
Mix the pulp with powdered capsicum, vinegar, powdered ginger, pepper, and salt.
Add beef gravy and simmer slowly for 15 minutes.
Strain and serve
Strain through a sieve and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main pulp and moisture that form the body of the sauce.
- Beef gravy
- Adds savoury depth and richness, and helps thicken the sauce as it simmers.
- Vinegar
- Adds acidity that brightens the flavour and balances the sweetness of the tomatoes.
- Powdered capsicum
- Adds a gentle pungent heat to the sauce.
- Powdered ginger
- Adds a warm, aromatic spice note.
The step that matters
Simmer slowly for 15 minutes. Gentle heat lets the sauce reduce and concentrate without scorching on the base of the pan. Too much heat can burn the sugars in the tomatoes and give a bitter taste.

Fit is the average pairing score against tomato, capsicum, vinegar, pepper, beef. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
