A sandwich spread is a condiment or topping used to enhance the flavor of a sandwich. The most common sandwich spreads are mayo (4 letters), JAM (3 letters), oleo (4 letters), DIJON (5 letters), and eggsalad (8 letters). Mayo is a creamy emulsion of oil, egg yolk, and either vinegar or lemon juice. JAM is a sweet spread made from fruit boiled with sugar and sometimes pectin. Oleo is a butter substitute made from vegetable oils. DIJON is a type of mustard made with white wine and spices. Eggsalad is a spread made from chopped hard-boiled eggs, mayonnaise, and seasonings.
