I found a bunch of blackberry bushes back in the 'forest' by our house. We rent, but the owners told us we were welcome to whatever berries we wanted. So I pick them (sometimes with my sisters' help) and sell them as well as fresh cobbler at the local farmer's market for some extra spending money.
I take the leftovers home and everyone eats them if I don't sell them or freeze them fast enough.
I make some with normal sugar, but most of them I make with Xylitol. A lot of the people who come to the farmer's market want sugar free things because they're diabetic, so I always sell more if I make sugar free. Since mom pretty much never buys 'real' sugar, its not a problem!
I make the regular ones with the berries on the bottom so I can easily tell the difference at the market.
