To make creme de cassis, blackcurrant berries are macerated, or left to steep, in alcohol in oak casks for at least two months to extract their flavour and colour.
In compliance with French law, the process is completely natural, with no fruit juice, colouring or flavouring added. Like other fortified wines, such as sherry or port, creme de cassis has a higher alcohol content (a minimum of 15 per cent ) than wine ( 8 to 14 per cent ).
A variation on the theme is the cardinal, also known as the communiste, depending on your political affiliation, in which cassis is combined with a chilled light-acidic red wine such as beaujolais.
Creme de cassis can enliven several food combinations. Try chicken with cassis, frozen cassis soufflé or cassis cake. Or simply pour it over vanilla ice-cream or pancakes (if warmed first, some of the alcohol will evaporate).
Creme de cassis is not meant to be aged in your cellar as the freshness of the fruit fades over time and it will start to oxidise, taking on sherry-like flavours.
Once a bottle is opened, it should be refrigerated to preserve its freshness and consumed within six weeks.
