Old Charley never knew nuthin' 'bout nuthin'.
Never bile yer plums or yer wine wo' clear.
I agree with the 3 lbs plums, 3 lbs shooger and 6 pints wairter.
Pick yer plums when they'm ripe on the trees, yo shud reely chop 'em in half an' tek the stoons aht but that can be a reet pain in the arris, chuck 'em in a bucket and pour over COLD wairter, crush in a campden tablet then smosh 'em to bits wi' a tairter masher. Put the lid on. Next day, add your pectolase, nutrient and yeasties. Stir at least twice a day then after 5 days strain the pulp out and add the sugar. Squeeze the straining bag as 'ard as yo can ter get all the joose aht. Leave it in the bucket for a few days more then transfer to yer demijar an' carry on like wot the bloke said.
