Measure out 1 tsp Salt, 1 tsp Ground Mustard Powder, ½ tsp Ground Allspice, ¼ tsp Ground Cumin, ¼ tsp Ground Paprika, ¼ tsp Black Pepper, ¼ tsp Garlic Powder, and ¼ tsp Onion Powder into a small bowl and set aside.
Add 1 cup Tomato Puree, ½ cup Vinegar, and ¼ cup Cane Sugar into sauce pan, whisking to combine. Bring mixture to a simmer over low heat.
Once the sugar has dissolved sift in the spices whisking to combine. Continue cooking until ketchup has reached your desired consistency.
Notes
Sifting in the dry ingredients helps prevent clumping and ensures a smoother sauce.
The intense, vaporous scent of the vinegar will also boil off to a milder scent when the cooking is nearly done. Trust your nose.
Low heat means low heat! Ketchup has a lot of sugar and is prone to burning. Slow and steady is the rule for most sauces, ketchup included.
No tomato sauce? No problem! You can mix tomato paste in equal parts with water and whisk it into the proper consistency. You can also use 1/4 cup tomato powder combined with 1 cup of water.
