Can I use different types of tomatoes for this relish?

Yes, you can use different types of tomatoes for this relish. Using a mix of varieties can add depth to the flavor. Roma tomatoes are excellent for a thicker consistency, while heirloom tomatoes can add a unique, rich taste. Ensure all tomatoes are ripe for the best results.

Slow Cooker Tomato Relish Ingredients

• 2 kg of tomatoes
• 1 kg of onions
• 1/2 cup of salt
• 1 long red chili
• 2 cups of brown sugar
• 2 cups of brown vinegar
• 2 tbsp of plain flour
• 1 tbsp of curry powder
• 1 tbsp of mustard powder
• Cracked pepper to taste

How To Make Slow Cooker Tomato Relish

1. Prepare the vegetables: Dice the tomatoes, onions, and chili, cover them with salt, and let them stand at room temperature for 24 hours.
2. Drain and cook: Drain the liquid from the tomatoes, onions, and chili, discarding the liquid. Pour the remaining mixture into the slow cooker, and add 1 cup of vinegar and cracked pepper. Cook on low for 1 hour, allowing the flavors to start blending.
3. Add sugar and spices: After 1 hour, add 1 cup of brown sugar to the slow cooker and stir well. Combine the remaining vinegar with the flour, curry powder, and mustard powder, then add this mixture to the slow cooker. Stir in the remaining brown sugar until it is well incorporated.
4. Continue cooking: Cook the relish on low for an additional 9 hours, stirring every 3 hours to ensure even cooking.
5. Jar the relish: While still hot, pour the relish into hot sterilized jars, ensuring that the jars are filled up to the rim. Once completely cooled, store the jars in the pantry. After opening, store the jars in the fridge to maintain freshness.

Is it necessary to cook the relish for the full 9 hours?

Cooking the relish for the full 9 hours ensures the flavors develop fully and the mixture thickens properly. However, if you’re short on time, you can cook it for a minimum of 6 hours, but the relish may be slightly less thick and flavorful.

Recipe Tips

• Use fresh ingredients: Always choose fresh, ripe tomatoes and onions for the best flavor. Fresh vegetables will make a significant difference in the taste of your tomato relish, so I highly suggest shopping at your local farmers’ market.
• Sterilize jars properly: Ensure that your jars are thoroughly sterilized before filling them with hot relish. This step is crucial for preserving your tomato relish safely. If I were in your place, I would not skip this step to prevent spoilage.
• Adjust the heat: If you prefer a milder relish, remove the seeds from the chili before dicing it. I love a bit of spice, but adjusting the chili allows you to control the heat level to your liking.
• Stir regularly: Stirring the relish every few hours while it cooks will help prevent it from sticking to the slow cooker. This also ensures that the flavors are evenly distributed throughout the relish, resulting in a better-tasting product.
• Use a plastic spoon: To avoid scratching your slow cooker, always use a plastic or wooden spoon for stirring. This will help maintain your slow cooker in good condition for future recipes.

Recipe Variations

• Sweet and spicy: Add a teaspoon of crushed red pepper flakes for an extra kick. This variation will give your tomato relish a sweet and spicy balance that I find absolutely delightful.
• Garlic lover’s delight: Add four minced garlic cloves for a richer, deeper flavor. If you love garlic as much as I do, this variation will make your relish even more savory and delicious.
• Herb infusion: Add a tablespoon of finely chopped fresh basil or oregano for an aromatic twist. Fresh herbs can elevate the flavor profile of your tomato relish, making it taste even more gourmet.
• Smoky flavor: Use smoked paprika instead of regular paprika to give your relish a subtle smoky taste. If I were in your place, I would try this variation for a unique and intriguing flavor.
• Lower sugar: Reduce the amount of brown sugar by half if you prefer a less sweet relish. This variation is perfect for those who are watching their sugar intake but still want to enjoy a tasty condiment.

What To Serve With Tomato Relish

Serve your Slow Cooker Tomato Relish with grilled halloumi, roasted garlic flatbread, cheese platter, quinoa salad, and avocado toast.

For a more substantial meal, try it with pulled pork sliders, or crispy chickpea patties.

How To Store Leftover Tomato Relish

In The Fridge:

Store leftover tomato relish in an airtight container to keep it fresh. Place the container in the refrigerator, ensuring it is tightly sealed. I highly suggest consuming it within 2 weeks to maintain the best taste and quality. Always use a clean spoon when serving to avoid contamination.

In The Freezer:

Tomato relish can be frozen, but I prefer storing it in the fridge for the best texture. If you must freeze, use airtight containers or freezer bags and freeze for up to 3 months.

How To Reheat Leftover Tomato Relish

Reheat your leftover tomato relish in a saucepan over low heat, stirring occasionally until warmed through. Avoid using high heat, as it can alter the flavor. Always reheat only the portion you plan to use immediately to keep the rest fresh.
