かす
noun
dregs; residue; lees
fooddaily-life
1. dregs; sediment; residue; lees
The solid matter left after liquid has been pressed or strained from a substance. Most commonly refers to sake lees (酒粕) or the residue from tofu production (おから).
I make pickles with sake lees.
Please don't throw away the coffee grounds.
There was residue at the bottom of the pot, so I washed it thoroughly.
2. worthless remnant; the worst part
Figuratively, something of no value — the leftover after everything good has been taken. Often used in the expression 絞りかす or 出がらし to describe someone or something drained of worth.
(しぼ)(かす)ような生活(せいかつ)(おく)っている
He's living a wrung-out, empty life.
The talented people quit that company, and only the dregs remain.

Written as (かす) for the physical residue sense (especially food-related) or (かす) for the figurative or general sense. In practice, hiragana かす is also common.

The most culturally significant usage is 酒粕(さけかす) (sake lees), which is widely used in Japanese cooking — for marinades, soups (粕汁(かすじる)), and pickling (粕漬(かすづ)). Sake lees are not waste but a valued ingredient.
