The last time I stared forlornly into a sink drain wondering how life could be so cruel was after I’d made a large pot of poultry stock. I’d set up my strainer and had just poured the pot contents through it. And there I stood with a strainer full of simmered-to-nothing vegetables, cartilage, skin, & bones and my drain plumbing full of disappeared stock.
I’d somehow forgotten the catch pot and had absentmindedly saved the solids, not the liquid!
