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.
This is so easy to do! Just bring the water in your stock pot to a boil and go ahead and prepare your bowl of ice water. Wash your squash thoroughly and then cut into 1/2 inch rounds. If you like to make zucchini bread then you may want to shred it instead of cutting it. If you have a large quantity then you may want to break it up into batches. Put your freshly cut squash into the boiling water for 2-3 minutes.
