Banks to prepare. I don't sterilize, just wash well. Cover pour over boiling water. Rinse Basil leaf. To lay in Bank. Tomatoes to wash up well. Fill jar tightly. Put another sprig or some leaves of Basil. Pour boiling water for 15-20 minutes. Drain the water in a saucepan, add salt and sugar and cook the marinade. Citric acid, I add directly to jar before pouring marinade. Roll up, tucking in for a day to cool. To get winter and enjoy!
