Which tool has an angled blade for spreading batters and creams inside pans?

The correct answer, which is the offset palette knife, is designed specifically with an angled blade that allows bakers to easily spread batters, frostings, and creams inside pans. The offset nature of the blade provides a comfortable grip and helps in reaching into the edges of the pan, ensuring an even application without disturbing the structure of the batter or cream. This is particularly useful in achieving a smooth and professional finish when working with delicate mixtures or when filling cake pans.

Other tools mentioned, like spatulas, while also used for spreading, typically do not have the same angle or design that makes them as effective for precise spreading in confined spaces. Whisks are used primarily for blending ingredients and incorporating air, not for spreading. Likewise, pastry brushes are intended for applying glazes or egg washes rather than for spreading batters. Understanding the specific function and design of each tool is crucial in pastry making, and the offset palette knife stands out for its unique capability in this context.
