Can I bottle toms the same way I bottle fruit? The Supersprout way. So prepare and pack into sterile kilners, cook in a low oven for 90 minutes, top up with liquid, seal with rubber grommits? If so, what would the additional liquid need to be - when I do fruit - pears, plums and greengages in the oven at the moment, I make a sugar syrup - would I make a light sugar syrup for the toms??
