Homemade tomato ketchup – an introduction

Remember I had made tomato sauce for the pizza in “how to make homemade pizza sandwich Turkish delight” then I got thinking that if I could just convert it into a tomato ketchup. Would it be tasty? You see we are almost there and it was a matter of blending it into a fine paste and thickening the resulting sauce into a ketchup.


The homemade tomato ketchup recipe is as follows


Tomato ketchup
Item Ingredients Percentage Weight Weight






1 tin tomatoes




1 tin tomato puree




2 onions


2 cloves of garlic


some oil for frying


corn starch 5 to 10

To make the tomato ketchup, we follow exactly the same steps as for the tomato sauce used on pizza.

Add the can of tomatoes and then the tomato puree. Do note the final quality of your sauce will be very dependent on the quality of the tomato puree. If the tomato puree is sour than the sauce will turn out to be very sour.

Just let it simmer and let some off the water content evaporate away. The above tomato ketchup procedure is the same as in the previous pizza recipe.

Once the tomato sauce has cooled down to room temperature add some corn starch and some sugar. Sugar is used to adjust the sour flavour of the tomato ketchup. Too much will make it too sweet. I found that the 15g I added was not sweet but others who tried it found it very sweet. If you are trying this out you could use about 5g. I do know from ex-tomato planters that tomato sauce manufacturers do add some cloves and or garlic and even papaya as a filler to thicken the sauce.

Blend the ingredient so that they will form a fine paste. This will allow the corn starch to mix well before heating to thicken the tomato ketchup.

My mom added the tomato ketchup while she was boiling the rice and it came out quite well. I did not notice the sweetness of the tomato ketchup but my mom found it very sweet. That means that if you are planning to make tomato rice leave the sugar out of the tomato ketchup recipe.
