When they arrived back home, they put all the berries together in a big bowl - there really were a lot - but there might have been quite a few more if some of the berries hadn't found their way into little mouths instead of into the boxes they'd taken (mentioning no names - Crackers and Custard!!)
That night they had hot blackberry and apple crumble for tea with lashings of ice cream melting over it. That was definitely yummy and well worth all the efforts they went to!!
Have a go at blackberrying yourselves. Take an adult with you, choose the quietest lane you can find and make sure you pack some plastic boxes to collect the blackberries in and some wipes or tissues for juice-covered hands, and try not to eat them all before you go home!
