Step 1

Add all of the ingredients to a saucepan and mix together.

Step 2

Bring the mixture to a boil.

Step 3

Reduce the heat and let the ketchup simmer for 40-45 minutes while stirring occasionally, until it's thick and has cooked down by about half.

Step 4

Use a stick blender, food processor, or standing blender to puree the ketchup until it is smooth. If the ketchup is too thin, return it to the heat until it's the desired thickness.

Step 5

Let the ketchup cool and store in the fridge until you're ready to eat it.
