Put the wine, spices, raisins, almonds, sugar and rind in a large saucepan and place on a low heat. You want to warm it slowly enough that the spices permeate the wine, but not heat it up so much the alcohol begins to evaporate. If it is a lunchtime affair, my mum will add a cup of orange juice and a cup of water, to make it slightly more fruity, and slighty less alcoholic. Skål!
