Do tomato-based sauces change/enhance flavour when left in the fridge? I cooked some green beans in a tomato-based sauce then ate some and left the rest in the fridge 3 days ago. I tasted it today, and it was better than I remember: is this a known phenomenon or am I not remembering right?
Most sauces, tomato based or not, will improve in flavour after being left overnight. This is also true of stews and casseroles. The received wisdom is that it gives the flavours a chance to 'marry' and blend, though I'm not sure of the science behind it.
