Bomba rice can absorb how many times its volume in water without bursting?

Bomba rice can absorb two or three times its volume in water without bursting.

That unusual absorption capacity is one reason bomba is prized for paella. The grains take in substantial liquid while remaining relatively intact, helping the finished rice hold its shape instead of collapsing into a sticky mass. Cooks therefore generally need more water or stock for bomba than for comparable rice varieties.

Bomba is a short- to medium-grain variety of Oryza sativa cultivated mainly in eastern Spain. It is closely associated with Valencian cooking and is commonly used in paella. The variety is noted for relatively high amylose and comparatively low amylopectin, a combination that limits stickiness and keeps the grains distinct.

Bomba is also associated with Spanish protected-origin growing areas such as Calasparra and Moratalla, and it is among Spain’s more expensive rice varieties. Its resilience does not mean it is impossible to overcook: timing, heat and the amount of liquid still determine texture. The key distinction is that the grains tolerate substantial absorption before bursting.
