A bolillo or pan francés is a type of savory bread made in Mexico and Central America. It is a variation of the baguette, but shorter in length and is often baked in a stone oven. Brought to Mexico City in the 1860s by Emperor Maximilian's troupe of cooks, its use quickly spread throughout the country.
It is roughly 15 centimeters (5.9 in) long, in the shape of an ovoid, with a crunchy crust and a soft inside known as migajón (Spanish pronunciation: miɣaˈxon). It is the main ingredient for tortas and molletes. It has a slash on top made with a slashing tool or bread lame, which permits the exhaust of steam and the expansion of bread without stressing its skin. A variation of the bolillo is the 'telera', which is very similar, but in this case, is usually softer and as a current trend sweeter. Other variations include bolillos made of alternate ingredients such as whole wheat, wheat germ, or flax.
