I see that I cannot can pesto because of the oil and I understand but I would like to be able to just can the basil with some water in it a little bit. What would be the time that I would have to can it and pressure or boil. Maybe like chili peppers in pressure canner? Using 4 oz jelly jars
There are no recommendations for canning basil.
Drying is an acceptable method which will yield an excellent product
You can also freeze basil with good results
