There is an abundance of wild blackberries around us. Last week we picked at least 10k\22lb of them. Some went into a Southern cobbler (recipe to come), but the rest were destined for jam\jelly.
My issue with blackberries: the seeds; I can't bear them. So seeds out, but I needed to know if they improve the flavour, so we ran an experiment.
We blended the blackberries raw, then de-seeded them using a kitchenaid with the fruit/vegetable strainer attachement. We then made two batches of jam\jelly, one with a muslin\cheesecloth bag of seeds and skin, the other without. To my great surprise our group thought that the jam made without seeds had the fuller earthier flavour.
I should also mention that the jams\jellies that we have been making are what I refer to as 'adult' jams and jellies. The 1-to-1 proportion of sugar to fruit makes sense for commercial producers, but using less increases the concentration of fruit and the flavour.
