Frumenty was a popular dish in Western European medieval cuisine. It is a porridge, a thick boiled grain dish—hence its name, which derives from the Latin word frumentum, "grain". It was usually made with cracked wheat boiled with either milk or broth and was a peasant staple. More luxurious recipes include eggs, almonds, currants, sugar, saffron and orange flower water. Frumenty was served with meat as a pottage, traditionally with venison or even porpoise. It was also frequently used as a subtlety, a dish between courses at a banquet.

Porridge is a food made by heating or boiling ground, crushed or chopped starchy plants, typically grain, in milk or water. It is often cooked or served with added flavourings such as sugar, honey, fruit, or syrup to make a sweet cereal, or it can be mixed with spices, meat, or vegetables to make a savoury dish. It is usually served hot in a bowl, depending on its consistency. Oat porridge, or oatmeal, is one of the most common types of porridge. Gruel is a thinner version of porridge and congee is a savoury variation of porridge of Asian origin.
