My wife makes great spaghetti sauce, but sometimes doesn't like to make it as often as I'd like. I use all the right stuff, and prepare the onions, garlic, red peppers and mushrooms separately before combining. Sadly I appear to lack her sense of balance and proportion in cooking. Mine is very good, but not nearly as good as hers.
However, I have found s sure way of motivating her. All I have to do is go into the kitchen and start assembling the ingredients and announce my intention to make a big batch, right now. Like a flash she's in the kitchen instructing me on how not to make a mess. Soon she gives up; kicks me out and makes it herself. I do get to caramelize the onions and peppers, shred the carrots, and saute the mushrooms, but that and pouring the wine are about it.
