I don't believe in twisting yourself into knots of excuses and explanations over the food you make.... Usually one's cooking is better than one thinks it is. And if the food is truly vile...then the cook must simply grit her teeth and bear it with a smile.
No matter what happens in the kitchen, never apologize.
Was it a sign of Creeping Decrepitude?
Always start out with a larger pot than what you think you need.
Never apologize for your cooking.
I always try to buy just what I need. You get ideas as to what's in season and what's best. I think if you have a preconceived idea before shopping, that makes it difficult. You have to have an open mind.
