Europe didn't grow many potatoes this summer. This means French fries will be 3cm shorter than usual. Europe had a very hot summer and there was very little rain, so farmers grew 25 per cent fewer potatoes. This increased potato prices. It also made potatoes smaller. Smaller potatoes means shorter French fries.
The potato shortage is big news in Belgium. Fries are Belgium's national dish. Many shops sell fries. Belgians call them "Belgian fries" because they say the fries were invented in Belgium. A farmer explained that long fries of 8 to 9 cm need big potatoes. This summer's smaller potatoes means fries will be shorter.
