The General Care of Cottolene
Exercise the same care and judgment with Cottolene as you would with butter, lard or olive oil; keep it in a moderately cool place when not in use, just as you would butter—so that its best qualities may be preserved.
Moreover, just because you occasionally buy strong butter or rancid lard which your grocer has kept in too warm a place, you do not denounce all butter or lard and give up their use; neither would it be fair to condemn Cottolene simply because your grocer may not have kept it properly. No fat will keep sweet indefinitely without proper care.
