Bring mixture to the boil, and allow to simmer for about 3 hours until all items soft and mixture is thick. Taste to see for adjustments – you my need to add a little sweetener depending on acidity of tomatoes. First batch I needed to, second batch not. Decant into clean class jars while still warm. Close and submerge in just boiled water for 5 minutes to complete the bottling process. I still keep it in the fridge as a precaution, but you don’t need to.
