摘要：
A method for hydrating yeast comprises several steps. A package comprising a thermochromic ink and an indicator is provided. A liquid is provided. The temperature of the liquid is measured by placing the package in contact with the liquid. The liquid is heated or cooled until the thermochromic ink indicates the liquid is within the predetermined temperature range. The liquid and yeast are combined. The package comprises a pouch, a thermochromic ink, and an indicator. The pouch is formed from one or more films sealed together to create an internal space. The thermochromic ink and indicator are arranged relative to each other to indicate when the liquid is within a predetermined temperature range. The thermochromic ink changes color when the liquid is within the predetermined temperature range.
