I come from a vaguely ethnic origin so learning to cook was something instilled at a young age. It usually started with asking dad for pizza and resulting in the usual “sure you can have pizza, as long as you make it yourself”.
So out came the frozen pitta dough out of the fridge,
the nasty tomato paste, some chopped ham and vegetables and crappy overstacked cheese.
Now this was a terrible pizza in retrospect but back then it was amazing cause you can eat pizza whenever you want (provided you have ingredients). So if you start basically getting your children to cook out of necessity and need for food but limit the categories to what they make. Then in the future you can mould a future basic chef.
I went through the terrible phase of cakes and cupcakes and crappy baking but the call for me to not be allowed to bake but instead provide main meals is what created the passion and level of experience i have. Im not saying to crush kids cooking but if you move into main meals at an early age then let the progression back towards complex cooking and baking it is remarkable.
I have gone through cookies to basic main meals to complex multi ethnic dishes, to bread-making back all the way to manipulating and experimenting with cookies.
