Step‑by‑Step Instructions for Tomato Relish
Step 1: Prepare Tomatoes
Start by blanching the ripe summer tomatoes to make peeling easier. Cut an “X” on the bottom of each tomato, then submerge them in boiling water for 20-30 seconds. You’ll know they’re ready when the skins begin to split. Remove them immediately and place in ice water to cool, making peeling a breeze.
Step 2: Salting
Once peeled, dice the tomatoes and onions into small pieces. In a large bowl, sprinkle the diced mixture generously with salt, tossing to combine. Cover the bowl with plastic wrap and let it sit overnight at room temperature. This process draws out moisture, enhancing the flavors necessary for your Tomato Relish.
Step 3: Strain
The next day, strain the tomato and onion mixture using a colander over a large bowl. Allow the mixture to drain for about 30 minutes or until excess liquid is removed. This step helps achieve that thick, chunky consistency essential for a perfect Tomato Relish, ensuring it won’t be too watery.
Step 4: Combine Ingredients
In a medium saucepan, combine the strained tomatoes and onions with vinegar, sugar, and mustard powder. Stir the mixture well until everything is well incorporated. This blend is the cornerstone of your Tomato Relish, enhancing its sweet and tangy profile.
Step 5: Cook
Place the saucepan over medium-high heat and bring the mixture to a boil. Once bubbling, reduce the heat to low and let it simmer uncovered for about 1 hour. Stir occasionally, keeping an eye on the texture; the relish will thicken and turn a deep red color, indicating it’s nearly done.
Step 6: Jar and Seal
Remove the saucepan from heat once the relish has thickened to your desired consistency. Carefully pour the hot Tomato Relish into sterilized jars, filling them while still hot. Seal each jar tightly with a lid and let them cool to room temperature before storing them. Proper sealing ensures the preservation of that summer flavor for months to come.
