There are several here, and they are no too bad.

I use this one for my 5 year old (candida problems). We originally used the rice syrup. My whole family has grown quite accustomed to the taste which has vague familiarity to HP Sauce (also made with dates)

8 ounces tomatoe sauce
1/4 c +3 tbsps brown rice syrup (I now use date sauce)
2 1/2 tbsps apple cider vinegar (or rice vinegar)
1/8 tsp garlic powder
1 tbsp water
1 tsp arrowroot starch
3 ounces tomato paste

In sauce pan, mix the tomato sauce, rice syrup vinegar, garlic. Mix water and starch together until dissolved and pour into saucepan. Stir until thickened slightly. Add paste and cook on low for about 20 minutes. Cool, bottle, and refrigerate.
** Recipie I first used indicated on low for only 5 minutes we found the longer the better. Original recipie also called for 2tsps raw suger which we omit.

In case you are interested Hunts makes a sugar free ketchup.

I order from this company and have been very satisfied with their products. We have many diabetics in the family and they appreciate the sugar free condiments. The cocktail sauce was very good and so was the ketchup.
