where is your wife from, ncage? that mght help us figure out how to get info across to her.
my wife learned to cook from a combo of rachael ray's 30 minute meals cookbooks, fannie farmer cookbook (for bigger things like roasts), from watching tv cooking shows, and from the excellent tuteladge of her loving husband.
i taught her how to make meatballs, grill meats, and make sauces/gravy; she taught me how to drive stick, lol.
keep up your positive attitude, be honest when thngs go well, and choke down the mistakes with a smile. it'll eventually get better and pay big dividends in the long run.
