Chili Sauce

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Make the sauce

  1. Combine the tomatoes, green pepper, onion, salt, sugar, vinegar, and spices in a large pot.

  2. Bring the mixture to a boil over medium heat.

  3. Once boiling, reduce heat and simmer for 30 minutes.

Bottle and store

  1. Pour the hot sauce into sterilized bottles and seal for storage.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Tomatoes
Provide the bulk, moisture and body that the sauce cooks down into.
Sugar
Adds sweetness that balances the acidity of the vinegar.
Vinegar
Adds acidity that sharpens flavour and helps preserve the sauce.
Onion
Adds savory depth and aroma as it softens during simmering.

The step that matters

Simmer for 30 minutes after boiling. Once boiling, the heat must be lowered so the sauce thickens gently. Simmering evaporates excess water and concentrates the flavours, while a hard boil can scorch the sugar and tomatoes on the bottom of the pot.

Swap the onion

How well each one fits the dish's main ingredients (tomato, pepper, sugar, vinegar):

  1. Capsicumfits better
  2. Cucumberfits better
  3. Mustardfits better
  4. Onionthe original

Fit is the average pairing score against tomato, pepper, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
