Kathryn’s Tomato Relish


• 3 kg ripe tomatoes
• 1 x kg finely chopped onions
• 1 kg white sugar 
• 2 x tablespoon curry powder
• 3 x tablespoons mustard powder
• Brown vinegar 
• Handful salt
• 1/2 teaspoon salt
• Corn flour to thicken around (3 tablespoons)


1. Peel and cut tomatoes in small segments, sprinkle with salt and refrigerate for 12 hours.

2. Peel and dice onions. Place in a separate bowl and cover with a handful of salt, cover and place in the fridge for 12 hours.

3. Drain onions & tomatoes well, add to a large stockpot & cover with brown vinegar, bring to the boil  fro 5 minutes.

4. Add 1kg of white sugar and stir through. 

5. In a small jug mix the curry power, mustard powder & cayenne pepper with a little brown vinegar.

6. Bring back to the boil and then simmer for 1 hour.

N.B. Sometimes you have to add more cornflour to thicken, it also depends on how much vinegar you add to the tomato & onions, so thicken to the desired thickness.
