Ingredients
For the Salad:
- 7 lbs. green tomatoes (30–40 medium-sized)
- 1.5 lbs. carrots (9–10 medium-sized)
- 3 lbs. onions (6–7 medium-sized)
- 6 tablespoons salt (3.5 oz or 100 g)
For the Syrup:
- 1 cup canola oil (200 g)
- 1 1/4 cups white vinegar (300 g)
- 1 cup sugar
- 5–6 whole black peppercorns
- 5 bay leaves
Instructions
Step 1: Clean and Sterilize the Jars
- Preheat your oven to 215˚F (100˚C).
- Wash jars and lids thoroughly with soap and warm water.
- Place the jars on the oven rack and let them dry for 20 minutes.
- Boil the lids in a small pot to sterilize them.
Step 2: Prepare the Vegetables
- Wash the green tomatoes, carrots, and onions thoroughly.
- Slice the tomatoes into 1/3-inch thick slices, discarding the stem area.
- Grate the carrots using the large holes on a grater.
- Peel and quarter the onions, then slice into thick pieces to maintain texture during cooking.
- Combine all the vegetables in a large mixing bowl and sprinkle with 6 tablespoons of salt. Mix well, cover with plastic wrap, and let sit at room temperature for 12 hours to release juices.
- After 12 hours, drain the excess juice from the vegetables.
Step 3: Make the Syrup
- In a large cooking pot, combine canola oil, white vinegar, sugar, black peppercorns, and bay leaves. Stir until the sugar dissolves.
- Add the drained vegetables to the pot and toss to coat them in the syrup.
- Cover the pot and bring to a boil over medium-high heat. Cook for 30 minutes, stirring occasionally to ensure even cooking.
Step 4: Pack and Process the Jars
- While the vegetables are cooking, ensure your jars and lids are clean and sterilized.
- Once the vegetables are cooked, transfer them while hot into the prepared jars, leaving about 1/2-inch of headspace. Pack tightly to remove air pockets.
- Screw the lids on snugly but not too tight to allow air to escape during processing.
- Place the jars into a canning pot, ensuring they are covered with 1–2 inches of water.
- Bring the water to a boil and process the jars for 15 minutes.
- Carefully remove the jars using a jar lifter and set them on a countertop to cool undisturbed for 12–24 hours.
Step 5: Check the Seals
- After 24 hours, check the jar seals by pressing the center of each lid. It should not move.
- If any jar fails to seal, refrigerate it and consume the salad within three months.
