Slow Cooker Tomato Capsicum Relish Ingredients

• 8 capsicums, any color you prefer
• 2 onions
• 1-2 deseeded chillies (adjust based on desired heat)
• 1 1/2 cups of water
• 2 cups of granulated sugar
• 1 1/2 cups of cider vinegar or white vinegar
• 4 ripe tomatoes, roughly chopped

How To Make Tomato Capsicum Relish in Slow Cooker

1. Prepare the Vegetables: Begin by deseeding the capsicums, onions, chillies, and tomatoes. Place them in a food processor and pulse until finely minced.
2. Combine Ingredients: Transfer the minced vegetables to the slow cooker. Add water, sugar, and vinegar, stirring to combine everything thoroughly.
3. Cook the Relish: Cover and set your slow cooker to high. Cook for 4 hours. Place a tea towel under the lid to trap condensation and prevent the relish from becoming too watery.
4. Thicken the Relish: If the relish is too runny, mix a tablespoon of arrowroot powder or cornflour with a little water to create a slurry. Stir this into the relish during the last hour of cooking to thicken.

Can I use bell peppers instead of capsicums in this relish?

Sure, you can easily use bell peppers instead of capsicums in this recipe. They are essentially the same vegetable, just known by different names in different regions. I find that using different colors really makes your relish look more visually appealing.

Recipe Tips

• Go for the Best Ingredients: To make a mouthwatering Tomato Capsicum Relish, it is of essence that you use the freshest ripest tomatoes, crunchy capsicums and hard onions available at your local market or supermarket.
• Make it Less Spicy: You can reduce spiciness if you are not a fan of extremely hot spicy foods by using fewer chillies or opting for milder hot ones. On the other hand, if you want to go up in these, add more chillies or opt for hotter kinds.
• Mind the cooking process carefully: Check your slow cooker often as you cook so that your relish does not become too thick or stick to its bottom. Occasionally stir if needed.
• Thicken It Carefully: Firstly dissolve the thickening agent in some little water so as to avoid lumping and then gradually mix it until it reaches your desired thickness.

Recipe Variations

• Add Fruits for Sweetness: Incorporate chopped apples or pears to the relish before cooking to add a natural sweetness and a more complex flavor profile.
• Experiment with Vinegars: Try using different types of vinegar like balsamic or red wine vinegar to tweak the acidity level and add a unique twist to the traditional recipe.
• Include Aromatic Herbs: Enhance the flavor by adding fresh herbs such as basil, thyme, or oregano in the last hour of cooking for a fresh and aromatic touch.
• Make It Smoky: Add a teaspoon of smoked paprika or a small amount of liquid smoke to give your Tomato Capsicum Relish a deep, smoky flavor, perfect for BBQs and meat dishes.

What To Serve With Tomato Capsicum Relish

How To Store Leftover Tomato Capsicum Relish
