# rolling boil

> English word · Noun

## Definitions
1. The boiling of a liquid rapidly with plenty of bubbling, which (unlike simmering) roils the liquid and thus may break up or alter the shape of ingredients.

## Etymology
Because the convection within the liquid produces strong currents that tend to swirl rapidly in circular patterns from bottom to surface and back again.
