Chili Sauce

Ingredients

Directions

Make the sauce base

  1. Combine the tomatoes, green peppers, onion, sugar, salt, and vinegar.

  2. Chop the peppers and onion.

  3. Boil the mixture for 1 hour.

Prepare the limes

  1. Take the limes while perfectly green, cut them in half, and clean entirely of the pulp.

  2. Put the limes in salt water strong enough to bear an egg for 6 weeks.

  3. Transfer the limes to cold water for 24 hours, changing the water every three hours.

  4. Boil the limes in saleratus water until tender enough to run a straw through (use one teaspoon salaratus per 6 quarts of water).

  5. Put the limes again in cold water, changing it several times.

Make the syrup and finish

  1. For each pound of limes, add 2½ pounds of loaf sugar and 3 pints of water.

  2. Boil the syrup for 15 or 20 minutes to clear it before adding the limes.

  3. Boil the mixture for 1 hour and 15 minutes.

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

What each ingredient does

Tomatoes
Provide the main body and liquid base of the sauce.
Sugar
Adds sweetness that balances the acidity of the vinegar.
Vinegar
Adds acidity that preserves the sauce and gives it sharpness.
Green peppers
Add vegetable bulk and a fresh, slightly bitter flavour to the sauce.
Limes (in the method)
Supply the characteristic tart flavour once softened and sweetened in syrup.

The step that matters

Boil the limes in saleratus water until tender. Stop when a straw passes through easily. Undercooked limes stay tough and fibrous, while overcooking breaks them down. Rinsing afterward removes the alkaline residue that would otherwise taint the flavour.

Swap the onion

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

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

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