Alcohol-soaked Christmas puddings could tip motorists over the drink-drive limit, research has revealed.
The festive favourite contains a mix of brandy, cognac, rum, sherry and cider, among other ingredients.
In some puddings the alcohol makes up a third of the ingredients, making it a 'dangerous dessert' for drivers.

The 12-Month Matured Decadent, sold by Harrods is the booziest Christmas pudding as it contains 30 per cent alcohol- which means that a portion of 100g contains the equivalent of a glass of wine or half a pint of beer.
It is followed by Sainsbury's, M&S and Aldi which all sell puddings containing up to 20 per cent alcohol.
Food and drink expert Martin Isark thinks the dessert should be sold with a warning on the label.

He told the Sun : 'A dessert that contains 30 per cent alcohol should say 'not suitable for children'.
'One with 30 per cent alcohol in the ingredients is fine for drinkers, but for children and drivers it is a dangerous dessert.
'Most consumers don't check the percentage of booze on the ingredient label and would be shocked to discover the copious amounts of alcohol they contain.'
