Alrighty. I'm not afraid to say I failed my first attempt at making fruit leather. Let's just say, wax paper - not the way to go.
This morning I was able to begin pulling the leather off the wax paper, but the liquid content in the berries was still too high and this broke down the waxiness of the paper. The leather also was not quite thick enough, I don't even think it was 1/4 of an inch thick, though it was definitely thicker when I spread it out initially. Seems fruit leather looses a lot of its bulk in the drying process.
So today I'll try again. I'm going to spread it out thicker and will be using something sturdier than wax paper. I'll keep you posted - I'm determined to get this right!
