Using Citric acid instead of lemon juice is an alternative as it doesn't change the taste of your tomatoes and you can use this amount
jar 500 ml (pint) 1 tbsp lemon juice (or) 1/4 tsp citric acid : 1/2 tsp pickling salt (optional)
jar 1 L (quart) 2 tbsp lemon juice (or) 1/2 tsp citric acid : 1 tsp pickling salt (optional)
Always use bottled lemon juice as the acidity is always the same.
