Eat slower than 10 minutes. My God have some company over. If you're spending 2 hours cooking there's no way doubling the recipe takes much longer.
Make the company or your significant other do the dishes. If you're in a situation where you're cooking for two hours then doing the dishes yourself, something is wrong.
Don't be like that. It's just that if you work that hard on food, have someone else enjoy it enough to want to do the dishes each time. And always have a dishwasher (the appliance), so it's easy.
