There are lots of books that will explaing technique, a lot of good ones are listed here, but only you will know which one is best for you and how you learn. I'd suggest checking out your local library before you buy any and give them a try.
I know for me personally I learned more watching people cook and listening to them while they were cooking, not just family, but cooking shows as well. I guess I am a strange one because I watch cooking shows a lot of the time for education and not for entertainment.
If books don't work for you, try Googling and seeing what videos are out there of cooking demonstrations and techniques, or find a cooking show that appeals to you and the type of food you like to cook/eat.
