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.
Blanching and shocking allows you to partially cook vegetables and cool them quickly so they retain their crunch. Use blanched vegetables in salads, pasta dishes, and as appetizers with dips. 1. Blanching and shocking can be used to cook almost any vegetable.
