aw sweetheart, it does really take practice. I couldnt boil an egg when i became a sahm. I literally learned everything from scratch. I still cant do a big dinner, like a full roast or christmas, but i would say that i'm a good cook.
My advice is to start small. Start with things that seem too easy to be tasty. Kara has given you some gorgeous recipes (that i am stealing!) and they seem to be pretty simple. and i totally agree with the girls, the crock pot is your best friend! Most crock recipes are just a matter of throwing everything in, stirring, and turning on.
Some other advice would be to invest in a really good cook book. My favorite one is
Delia Smith but its very british and might not be much help to you. Liz would be the best person to ask for a recommendation from the states! but this book went into detail about the most basic of dishes, and more importantly
why I messed up.
I'll try and find some of my simple recipes, most of mine are just me throwing whatever is in the fridge into a pan tho!
