Chemistry is the scientific discipline involved with compounds composed of atoms, i.e. elements, and molecules, i.e. combinations of atoms: their composition, structure, properties, behavior and the changes they undergo during a reaction with other compounds. Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds.
squash requires a brief heat treatment, called blanching, in boiling water or steam, to destroy the enzymes before freezing. Cook (blanch) the squash for 3 minutes. Begin counting the blanching time as soon as you place the squash in the boiling water.
Transfer the carrots to the bowl of icy cold water. Set the timer and let them cool for the same amount of time as they spent blanching. If they blanched for 3 minutes, let them cool for 3 minutes. 5. Take them out of the water when the timer goes off. Drain the carrots and pat them dry with a paper towel.
