The cost of an average Christmas dinner for a family of four has risen to €34.74, up 2% on last year, driven mainly by the price of turkey and Christmas vegetable staples.
New figures from Kantar show that brussels sprouts and mince pies have seen an increase of over 10% in price compare to this time last year. Carrot prices are up 6.6%, parsnips are 12% more expensive, while the cost of potatoes are up 4.3% and turkey prices are up 5.1%.
However, the price of cranberry sauce is down 9.4%, while the price of gravy is also 4.7% lower.
