I was in charge of next-doors runners last week while they were away, I picked some for the other neighbour, my friend had a load, and then we sliced a load.
I had quite a production line going, boiling water, cold water, iced water, drain in colander, bag.
Managed to do 8 bag loads, not bad for one days pickings.
Boiled them for about 3 mins, then dunked in cold, then iced.
Hope I've done it right cos I promised friend who helped me pick and slice them that we'd have them for Christmas Dinner.
I do get a feeling of satisfaction when I see them waiting for me in the freezer though.
