In the summer, the French will face a sad sight in supermarkets, there will be no mustard on the shelves.
The shortage will occur due to the lack of shallot seeds required for the production of this sauce.
A severe drought in Canada, poor harvests in France and the war in Ukraine have combined to reduce the supply of shallot seed available to producers.
Because of this, the price of mustard in France has increased by 10 percent, and some stores are having difficulty filling the shelves.

France imports most of its seeds from Canada, but there was a big drought in that country last year that destroyed the crops.
Not all droughts are the result of climate change, but excess heat in the atmosphere pulls more moisture out of the ground, and droughts are getting worse.
The planet has already warmed by about 1,2 degrees Celsius since the industrial era began, and temperatures will continue to rise unless governments around the world significantly reduce emissions.
Harvests of domestic scallion seeds in France have not given satisfactory yields for three years in a row, and the last time the reason was a wet winter and a cold spring.
Lik Vandermeson, CEO of France's third largest mustard producer The Queen of Dijon, told the BBC that production is 20 to 25 percent lower than usual.
"The market is empty, everything is already reserved and we have difficulties to get seeds," he said.
Producers in France had originally hoped to import additional safflower seed from Russia or Ukraine to make up for shortages, but due to the war, this was not possible.
The war disrupted global supply chains for many agricultural products.
Russian attacks and the blockade of Ukrainian Black Sea ports, as well as Western sanctions against Moscow, have greatly limited the amount of food that both countries export to the rest of the world.
Earlier this week, the United Nations warned that the invasion could cause a global food crisis that could last for years.
And in the UK, the suspension of sunflower oil shipments from Ukraine last month led to supermarkets limiting the number of bottles of cooking oil per customer.
