The term 'STICK IN THE REFRIGERATOR' can be solved by two crossword solutions: OLEO (4 letters) and MARGARINE (9 letters). OLEO is a shortened form of the word oleomargarine, which is a butter-like spread made from vegetable oils. MARGARINE is a similar product, but it is made from hydrogenated vegetable oils. Both products are typically sold in stick form and must be kept refrigerated to maintain their texture and flavor.
