No, the evidence presented does not prove what you assert.
Modern mothers are much more adventurous in the kitchen and can prepare 25 per cent more dishes than their mothers, research suggests.
Being able to cook more things is not the same as being able to cook better.
I, for example, am a lousy cook and I\’m a lousy cook at cooking everything from spag bog through to pheasant in port and cream sauce. I\’m terrible at many more than 25 different dishes.
My father has perhaps four recipes and at at least two of them (his bread and his baked apples) he is an excellent cook.
Variety is not necessarily a signal of excellence.
