Step 1: Prepare the Ingredients
Sterilize the bottles and lids by boiling them or using a dishwasher’s sterilization setting. Slice the onions and chop the garlic in advance so they’re ready to go.
Step 2: Cook the Tomatoes
Introduce the 4 kg of tomatoes into a large pot on medium heat. No need to peel or seed them. Add the chopped garlic and all the dry spices (1 teaspoon cinnamon powder, 1 teaspoon allspice, 1/2 teaspoon crushed cloves, 1/2 teaspoon yellow mustard seed, and 1/2 teaspoon cumin powder). Add the sliced onions and stir to combine.
Step 3: Simmer the Ingredients
Simmer the mixture on low heat until the tomatoes soften, about 30-45 minutes. Stir occasionally to prevent burning.
Step 4: Add Sweetness and Smokiness
Once the tomatoes are soft, add 320 grams of dark brown sugar. Then add 3 tablespoons of red pepper concentrate (or unsmoked paprika powder). Add 2 tablespoons of smoked paprika powder. Stir the mixture well to blend in the sugar and spices, allowing the sauce to become fragrant and smoky. Add 4 teaspoons of salt, stirring again.
Step 5: Simmer Again
Simmer the sauce for another 10 minutes, stirring occasionally to avoid sticking.
Step 6: Add the Vinegar
Add 350 ml of apple cider vinegar (or more if you prefer a tarter sauce). The vinegar helps lower the pH, making the sauce shelf-stable. Aim for a total of 375 ml of vinegar in the recipe for a balanced tartness. Let the sauce continue to simmer for about 10-15 minutes. Watch for the sauce to reduce by about 1/4 in volume.
Step 7: Blend the Sauce
Blend the sauce carefully (in batches, if necessary) until it’s smooth. Use an immersion blender or transfer to a countertop blender. Return the blended sauce to the cleaned pot. Bring it back to a simmer, stirring to ensure everything is evenly mixed.
Step 8: Adjust Seasonings
Taste the sauce and adjust the salt or vinegar as needed. If the sauce is too sweet or lacks tartness, add more vinegar to taste. Adjust salt if necessary (the total could be up to 5 teaspoons).
Step 9: Final Reduction
Simmer the sauce for an additional 5-10 minutes, ensuring all flavors meld together and the sauce reaches the desired consistency.
Step 10: Bottle the Sauce
Fill the sterilized bottles with the hot BBQ sauce, leaving a small gap at the top. Tightly secure the lids to ensure a good seal.
Step 11: Water Bath Canning
Place the filled bottles in a tall pot or water bath canner. Make sure the bottles are submerged, with the water covering the lids by at least 1 inch. Boil the bottles for 15 minutes to properly seal and preserve the sauce. Be careful when handling hot bottles—they may be slippery and unstable when upside down.
Step 12: Cool and Store
Let the bottles cool overnight before handling. Once cooled, store the BBQ sauce in a cool, dark place like a pantry. It will be shelf-stable for up to 1 year.
Now your smokey BBQ sauce is ready to enjoy anytime!
