When I first met my husband he couldn't even make a cup of coffee - his mother did all the cooking at home and he survived on take-aways and junk food when he went to uni - so I taught him the basics, but still did most of the meal planning/shopping/cooking myself.
After the arrival of our two children, when I went back to full time work, he started to cook a little more as long as there was a recipe and all the ingredients were to hand.
Then four years ago I was diagnosed with a brain tumour and he took early retirement, so he has gradually taken more and more responsibility for cooking our meals. It was difficult at first and the kitchen did resemble a disaster zone, but he has improved over time. So much so that now he does all the cooking and most of the clearing up. However, he does love a gadget and our stock of knives, rice cookers, egg slicers, mandolins, graters, garlic presses, pots and pans keeps expanding. I still do most of the meal planning, but in this last year he has started to search for recipes online - we had a really good made-from-scratch chicken curry last night - I just had to show him how to peel and grate the fresh ginger.
Friends say I'm so lucky, but they won't let their husbands into their kitchen, complain about the extra mess he uses every pan, critisize and belittle their efforts - is it any wonder their husbands don't cook?
