Homemade Ketchup and Sauces for Winter

The Flavor + Safety Basics (quick and clear)

• Acid: Tomato and fruit-based sauces need enough acidity (target pH under 4.2–4.4 for canning). The simple home-cook proxy is adequate vinegar or citrus and not diluting with low-acid ingredients.
• Sugar and salt: Preserve flavor, bind water, and stabilize texture. You can reduce both within reason, but see notes in each recipe for the canning-safe floor.
• Heat processing: For shelf-stable storage, ladle hot sauce into hot, clean jars, leave headspace, wipe rims, apply lids, and boil in a water-bath canner for the time listed. Otherwise, cool and refrigerate (3–4 weeks) or freeze (3–4 months).
• Texture: Aim for slow simmer and wide pots for quick reduction. For ultra-smooth ketchup, finish with a blender and pass through a fine sieve.

Master Tomato Ketchup (classic, bright, pourable)

Yield: ~4 half-pints (4 × 240 ml)

Ingredients

• 2.5 kg ripe tomatoes (canned whole tomatoes work off-season—2 × 800 g cans + one 400 g can)
• 1 large onion, chopped (~250 g)
• 1 red bell pepper, chopped (optional but great body)
• 2 cloves garlic, minced
• 120 g brown sugar (about ½ cup, lightly packed) — up to 180 g for classic sweetness
• 240 ml apple cider vinegar (5% acidity)
• 1½ tsp fine salt (start here; adjust to 2 tsp to taste)
• Spice sachet (tie in cheesecloth): 1 tsp mustard seed, 1 tsp allspice berries, ½ tsp black peppercorns, ½ tsp clove, 1 small cinnamon stick, 1 bay leaf
• 1 Tbsp tomato paste (optional, for color pop)

Method

1. Combine tomatoes, onion, pepper, garlic, and spice sachet in a wide pot. Simmer 25–30 minutes until soft.
2. Fish out sachet. Blend until smooth. Return to pot; add sugar, vinegar, salt, and tomato paste if using.
3. Simmer over medium, stirring often, until thick and glossy (30–45 minutes). Aim for a slow ribbon when you drag a spoon.
4. Season: Balance sweet/tangy/salt; add a splash more vinegar if it tastes flat.
5. Jar hot.
   • Canning: Ladle into hot jars leaving ½ inch (1.25 cm) headspace. Process 15 minutes (pints/half-pints). Cool 24 h; store 1 year.
   • Fridge: Cool and refrigerate up to 1 month.

Flavor note: For a fry-friendly ketchup, keep sugar at ~150–180 g. For cooking/glazes, the leaner 120 g version is more versatile.

Canning Workflow (applies to recipes above marked for canning)

1. Wash jars, lids, and rings. Keep jars hot (in simmering water or a 90–95 °C oven).
2. Bring a canner to a rolling boil.
3. Ladle hot sauce into hot jars, leaving ½ inch headspace (check each recipe).
4. Remove air bubbles with a clean utensil; wipe rims with vinegar; apply lids fingertip-tight.
5. Process at a full rolling boil for the time listed (start timing when boiling resumes).
6. Cool undisturbed 12–24 h. Check seals; label and store in a cool, dark place.

---

Storage & Use

• Shelf-stable (processed): Up to 12 months unopened.
• Refrigerated (unprocessed): 3–4 weeks.
• Frozen: 3–4 months (leave headspace).
• Great uses: glaze roast roots with BBQ sauce; toss meatballs in plum sauce; whisk ketchup into mayo for fry sauce; fold onion relish into grilled cheese; finish soups with a spoon of pepper–tomato sauce.

Troubleshooting

• Too thin: Keep simmering; pectin-free tomato sauces thicken by evaporation.
• Too sharp (vinegary): Simmer 5–10 minutes more or round with a teaspoon of sugar or a knob of butter (for non-canned serving).
• Bitterness: Over-reduced spices or scorched sugars. Lower heat, stir more, consider swapping brown sugar for maple/honey next batch.
• Separating ketchup: Blend thoroughly and add 1–2 Tbsp tomato paste to help emulsify.
