Why has my cordial/jam gone mouldy?
You may have used too little sugar, mouldy or bad fruit, or fruit that has not been adequately cleaned. Mould can also be caused by inadequately sterilised jars, or by storing the jars in warm and moist conditions. When your jam or marmalade is ready, it’s important to quickly pour it into the jars, filling them right to the top. Always throw away mouldy preserves. Never eat them, since certain moulds can form toxins.
