because they share certain flavour compounds. Ahnert, himself an amateur molecular gastronomist, was intrigued by the anecdotal suggestion that the reason some foods go well together is

But in East Asian and Southern European recipes, the trend was the opposite the ingredients were less likely to share flavour compounds.

for example share flavour compounds with many other foods. Once these foods were removed from the analysis

when the team removed the most common ingredients that shared the least flavour compounds (beef, ginger, pork, cayenne, chicken and onion) from the analysis,

"It s clearly something different from shared compounds, he says.""To get a clearer idea of

I want to look at better data on flavour compounds. He has contacted therefore the owners of professional databanks to find out how much of each flavour compound is present in an ingredient.

but not the same flavour compounds, are used together. Other studies into ingredients and recipes have been conducted.
