I managed to clean the kitchen and do the dishes every evening for two weeks in a row now and it is a start to be nice to tomorrow me. If it becomes a habit, I will try to do more, but for now it is hard enough, but also so, so satisfying the next morning! Past me, today me and tomorrow me are a team!
Tomato sauce and everything hot tomato, especially if you use canned tomatoes, needs a bit of sugar. It makes it 100% better. It does not make it sweet, but all the flavors of the tomato just pop while otherwise it is only sour and bland.
