Shaped like a football and about 6 inches long, a bolillo is a Mexican roll made from dough similar to that for a French baguette. Bolillos have crisp brown crusts and light, chewy interiors and are most often used to make tortasMexican sandwiches. A telera is very similar but scored to divide it into three sections.
