A spike in the price of hazelnuts due to bad weather and disease means the cost of the spread could be about to skyrocket.

Hazelnuts are more popular than ever — high in protein, fibre, vitamins and folate — and many people say they taste delicious when combined with chocolate in a breakfast spread.

Turkey is home to about 70 per cent of the world’s hazelnut crops.

A spring frost has damaged much of those crops, according to reports, threatening this year’s harvest. While industry forecasts predicted a yield of 800,000 tonnes, those have since been revised to 540,000 tonnes.
