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.
Step 4. Slice the squash into 1/2-inch pieces, cutting up only the amount of squash that will fit in one pot of boiling water. If you leave cut squash for more than 30, it will begin to discolor. Step 5. Drop the squash into the boiling water, cover and blanch for three minutes.
