Learn by cooking one recipe at a time..
Whenever I want to make something different, I go online and read up about different recipes. I will look for a few things, one.. ingredients (does it have ones that my family will like) two, does the recipe have good reviews.. lastly, how easy or not is the recipe and does it appear that I can do it....
Sites I like are myrecipes.com foodnetwork.com ,marthastewart.com and Test Kitchens of America.
I will say that NOT all recipes I have ever tried by some famous person and or their book has turned out great... yet some have..
Here's an example.. I made Rick Bayless' "Choco Flan Cake" (aka, Impossible Cake") his name for it.. :)
The first time I made it was a bit messy.. DUH.. I used a springform pan (as I had done for many other cakes) but this cake was different , you also pour in Flan.......... guess what happened, my FLAN.. fled.......... yes, it all poured out of pan seal......... WAH!!!!! LESSON LEARNED.... so mishaps will happen.. you just have to keep trying out new things..
NOW, I can make that cake like a pro... Even Rick would be proud..
Monday, for my husband's birthday, I am going to try out a new recipe I saw on Foodnetwork... "stuffed Pork chops" now I have NEVER stuffed a pork chop in my life, but I aim to try it out...
Basically, cooking is trial and error.. don't be afraid to just try something out... start with simple recipes and then advance as you go along..
P.s. that those Test Kitchens of America has some great tips..... what's good too is that they EXPLAIN exactly why they do this or not..
check it out sometime..
good luck to you
