The term CATERER'S NEED is composed of three words: STERNO (6 letters), HIRER (5 letters), and SAMOVAR (7 letters). Sterno is a type of fuel made from denatured alcohol, which is used to heat food for catering events. A hirer is someone who hires or contracts a caterer for an event. A SAMOVAR is a heated metal container traditionally used to make and serve tea. All three of these items are necessary for a caterer to provide their services.
