Tomato Red Onion Relish in 55 Minutes

Instructions:

1. Dice the tomatoes and red onions into uniform 1/4 inch pieces to ensure even cooking.
2. Combine the diced tomatoes, red onions, and minced garlic in a large heavy-bottomed saucepan.
3. Stir in the apple cider vinegar, brown sugar, sea salt, black pepper, and red chili flakes.
4. Bring the mixture to a boil over medium-high heat, then immediately reduce the heat to a simmer.
5. Let the relish bubble gently for 35–45 minutes until the liquid is reduced by half and the onions are translucent and mahogany-colored.
6. Stir in the lemon juice during the final 2 minutes of cooking to brighten the flavors.
7. Remove the pan from the heat and allow the relish to cool slightly in the pan to thicken before transferring to sterilized glass jars.
