It’s time to get out your mason jars, sterilize them, and get ready to start canning those extra tomatoes. Except this time, we’re going to preserve the tomatoes as ketchup!

Whether you planted a few too many tomato plants, or just want to make your own ketchup from the ripe and mouthwatering deliciousness of the local farmers market, you’re in for a treat!

The ketchup you’ll be canning has a tasty balance of sweetness, acidity, and spice.

Once you open the canned product, use within 2-3 weeks.

This recipe makes approximately 750ml, or 2-3 small jars.

You’re looking at about 1 hour and 15 minutes from start to finish. The unopened product will keep for about 3 months.

We’d love to see your finished product! Send pictures to photos@putitinajar.com and we’ll put the pictures up here for everyone to see!
