Does anyone know if there is a reason that Lime juice cannot be used in place of the Lemon juice in Jams? The reason I ask is that my farmer's market (at least the stall that my friend works in and gives me DEEP discounts at) does not currently have lemons, but has tons of limes. And lemons being $1 for 2 at the grocery store, I was wondering if they would indeed be interchangeable in this instance.
Also, I have read that bottled lemon juice is preferable to the fresh-squeezed by several jammers as the acidity level is more consistent. Is there any truth to this? What do you think? Thank you!
