Being brainy means you have a well stocked pantry. Mostly, you need to have on hand basic items: butter, heavy cream, olive oil, coconut oil, pasta, rice, onions, garlic and dried herbs plus salt and pepper. When cooking with these basic items, you can turn any meat or vegetable into a gourmet meal and you won't need a recipe. You need good judgement and common sense, that's being brainy. And, that's easy. Just know what you like and don't like. Know your taste buds; most people are like you. They don't like too much salt or too much sugar neither taste good nor are they good for you.
Take stock and get ready to cook!
