A quick response here as I'm late for work but..... 1. Read, read, read. From many sources. Practice. Cover all the main techniques, and most importantly, understand the recipes. You should always know what is happening to your food when you add certain ingredients e.g. why a few drops of lemon or vinegar in a meringue?! 2. Bin or homeless guy. That's part of learning! But be positive, every mistake (should) be something learned. 3. Good question. There's no easy answer. Even if you order one at a restaurant to compare how do you know that the pastry chef there isn't rubbish!? Learn to trust your own instinct and judgments. 4. Experience. But this book is fantastic, and it covers classic to obscure pairings, with recipes. BOOK LINK Good luck to you.
