My grans hidden stacks for Christmas included rum butter for the pudding ,home made pudding and Christmas cake fed with Navy rum,also Grasmere gingerbread. Cumberland sauce and a big joint of ham that seemed to boil all day.
One also made her own wine that tasted like port from a reedy plant she called a Burnett we helped her pick them in the late summer. Crab apple jelly,pickled onions and pickled red cabbage all to accompany the Christmas roast and cold ham.
Then like others the Newberry fruits,boxes of dates with a fork sugared orange and lemon slices and a special Irish brand of chocolate Brazil nuts.Also non alcholic wine for the children they called raisin wine that they seemed to buy from the chemist.
My mums was much the same only the spare bedroom was full of Christmas cakes that she made and decorated for all the extended family, I hate the smell and taste of Christmas cake I think because it permeated the house from October onwards.
