What is a knob of butter? A "knob of butter" is an informal term used to describe a small,
roughly tablespoon-sized portion of butter. It is not an exact measurement, and the amount can vary
depending on the context or individual preference. Typically, a knob of butter is a small piece that
is cut or broken off from a larger block or stick of butter. This term is commonly used in cooking
and recipes when an approximate amount of butter is needed, often for sautéing, frying, or adding a
bit of richness and flavor to a dish. When using a knob of butter, it is generally understood
that precision is not critical, and the actual amount can be adjusted based on personal taste.
