Use citric acid instead of lemon juice when canning


I am making wine jelly and have run out of lemons. I have some citric acid in the pantry. Can I use the citric acid instead? The jelly calls for half a cup of lemon juice. If I can use it, how much citric acid would I use?

Best Answer

Yes, you can. In fact, many canning and jarring recipes specifically call for citric acid.

Presumably you are using citric acid in its dried, crystalline form. In that case, a solution of around 4% citric acid (e.g. 4gm in 100ml of water) should be around the same strength as lemon juice.
