A waffle is a dish made from leavened batter or dough that is cooked between two plates that are patterned to give a characteristic size, shape, and surface impression. There are many variations based on the type of waffle iron and recipe used. Waffles are eaten throughout the world, particularly in Belgium, which has over a dozen regional varieties. Waffles may be made fresh or simply heated after having been commercially cooked and frozen.
The word waffle first appears in the English language in 1725: "Waffles. Take flower, cream..." It is directly derived from the Dutch wafel, which itself derives from the Middle Dutch wafele.
While the Middle Dutch wafele is first attested to at the end of the 13th century, it is preceded by the French walfre in 1185; both from Frankish wafla 'honeycomb' or 'cake'.
Other spellings throughout modern and medieval Europe include waffe, wafre, wafer, wâfel, waufre, iauffe, gaufre, goffre, gauffre, wafe, waffel, wåfe, wāfel, wafe, vaffel, and våffla.
In ancient times the Greeks cooked flat cakes, called , between hot metal plates. As they were spread throughout medieval Europe, the cake mix, a mixture of flour, water or milk, and often eggs, became known as wafers and were also cooked over an open fire between iron plates with long handles.
Waffles are preceded, in the early Middle Ages, around the period of the 9th–10th centuries, with the simultaneous emergence of fer à hosties / hostieijzers (communion wafer irons) and moule à oublies (wafer irons). While the communion wafer irons typically depicted imagery of Jesus and his crucifixion, the moule à oublies featured more trivial Biblical scenes or simple, emblematic designs. The format of the iron itself was almost always round and considerably larger than those used for communion.
The oublie was, in its basic form, composed only of grain flour and water – just as was the communion wafer. It took until the 11th century, as a product of The Crusades bringing new culinary ingredients to Western Europe, for flavorings such as orange blossom water to be added to the oublies; however, locally sourced honey and other flavorings may have already been in use before that time.
