knob

I melted a knob of butter in a small saucepan, then a spoonful of the dried leaves.

Its hoodlike structure is called a spathe, which envelopes a bulb-shaped structure called the spadix, a fleshy knob dotted by dozens of tiny, petal-less yellow flowers.

The knobs felt like a thousand hands had worn them soft over time.

A dinner roll the size of a closed fist, its warmth melting a knob of cinnamon butter into something almost scandalous.

If you'd like to amp up the richness, a knob or two of butter added directly to the surface of the steak about halfway through the cooking process will help add moisture, color and flavor.
