I recently got turned onto "Great Depression Cooking," a youtube series starring a sassy nonagenarian (who just passed away). I love how slowly she cooks, and how she never measures anything. Most of her recipes are nearly vegan (you know, the Great Depression...).
In this episode on tomato sauce, she makes her own tomato paste from scratch to flavor the sauce.
"You know how tomato paste looks--like paste. And it's red."
"You don't need a timer if you're using your brain."
