We all grew up seeing our parents and grand-parents, who lived through the Great Depression, wars, and/or famines, take care — to the extreme — to not let any drop of sauce from a can, any heel of bread or any minute shred of fish off the bone ever go to waste.

Not on their watch.

And now, not on ours, either.

With the pandemic creating food shortages — both real and exaggerated ones — we find ourselves looking at food much differently now, treating everything with the reverence it deserved all along.

The very bottom stems of parsley that I once tossed? No more. Now, they get finely diced and tossed into salads and soups. Those radish tops I once never looked twice at? Now, I savor them sauteed in an egg scramble.

The leftover ricotta I had from making lamb meatballs? Not that I would deign to ever throw something like that out, but these days, it takes on an outsize importance. Yes, that leftover ricotta that I once just nonchalantly enjoyed with berries for breakfast the next day, now seemed too good for that. Clearly, it should be destined for something far more special, I thought.

I found exactly that in “Louisa’s Cake.”
