How to Make Sloppy Joe Starter

Prepare Your Jars: Begin by cleaning your canning jars and lids with warm, soapy water. Ensure there are no chips or bubbles in the glass that could ruin your seal.
Wash Your Produce: Rinse all your vegetables thoroughly to remove any dirt and pesticides.
Preheat Your Oven: Set it to 375°F (190°C) so it’s hot and ready for your veggies.
Chop the Vegetables: Finely chop the green and red bell peppers, followed by dicing the onions.
Prepare the Baking Sheet: Line a large rimmed baking sheet with aluminum foil and lightly coat it with cooking spray to prevent sticking.
Bake the Veggies: Spread the chopped peppers and onions on the baking sheet. Sprinkle the salt and pepper over them, mixing well. Bake for 20 minutes until the vegetables are tender and slightly browned, stirring occasionally.
Prepare Your Canner: If using a water bath canner, place your canning rack in it, and warm your pint jars while the water heats. Use enough water to cover the jars by 2-3 inches. For a steam canner, follow the manufacturer instructions for water levels.
Combine in Dutch Oven: Transfer the baked vegetable mixture into an enameled Dutch oven or a stainless-steel pot. Stir in the 1 can of tomato paste, cooking over medium heat for about 5 minutes until the mixture thickens and the edges bubble slightly.
Add Remaining Ingredients: Stir in 4 cans of tomato sauce, 1 cup of apple cider vinegar, 1/2 cup of Dijon mustard, and 1/4 cup of brown sugar. Bring this mixture to a boil to start combining those incredible flavors.
Simmer: Lower the heat and allow the mixture to simmer uncovered for about 5 minutes, stirring frequently, until it thickens to your liking.
Fill the Jars: When your jars and the sloppy joe starter are hot, remove jars one at a time from the canner using tongs. Ladle the hot starter into each jar, leaving a 1/2 inch (1 cm) headspace. Use a de-bubbler to remove any air bubbles, adjusting the headspace as needed.
Seal the Jars: Wipe the rims of the jars clean to ensure a good seal. Center a lid on each jar and screw down the band to fingertip tight.
Process the Jars: Place them back into the canner. For water bath canning, lower the rack and ensure the jars are covered with at least 2 inches of boiling water. Process pint jars for 20 minutes, adjusting for altitude. For steam canning, follow your canner instructions.
Cool Down: After processing, turn off the heat and let the jars sit in the canner for an extra 5 minutes before transferring them to cool on a wire rack.
Label & Store: Once cooled, remove the canning rings, wash jars, and label with the recipe name and date. The starter can be stored in a cool, dark place for up to a year.

Storing & Reheating

Store leftover Sloppy Joe Starter at room temperature for up to a year if properly canned. For opened jars, refrigerate in an airtight container for up to 2 weeks. You can also freeze the starter in freezer-safe bags or containers for up to 3 months. When you’re ready to enjoy, simply reheat it on the stovetop over medium heat for about 10-15 minutes until warmed through. Note that freezing may change the texture slightly, but a good stir should refresh the sauciness.

Chef’s Helpful Tips

Avoid Overcooking the Vegetables: Keep an eye on your veggies while roasting; you want them tender, not mushy.
Fresh Ingredients: Use fresh produce for the brightest flavors. This is not the time for limp peppers!
Check Your Seal: After cooling, ensure the jar tops are domed and don’t flex when pressed; this ensures a good seal.
Add Spice: For a kick, try adding some crushed red pepper flakes or a dash of hot sauce to the mix!
Make Ahead: This Sloppy Joe Starter can easily be made a day in advance to save time on meal day.

There’s something truly rewarding about creating a Sloppy Joe Starter from scratch. It not only brings a nostalgic sense of comfort but also allows you to control what goes into your food.
