The Differences Between Simmer and Boil

Simmer and boil are actually two methods of cooking which are virtually identical in nature and, therefore, many people remain baffled regarding their difference. Nevertheless, there are some subtle differences between the two.

Simmer

While cooking many recipes, quite often the heat has to be kept down for it to be appropriately cooked. Simmering happens right underneath the boiling point, ranging between 185-205 degrees Fahrenheit. It is usually known as “gentle boil” since this method does not allow water to boil vigorously. You will see bubbles rise towards the top—however, they are small and not too fast.

Boil

Boiling occurs when bubbles break free in your cooking liquids and rise to the surface when it actually reaches the boiling point. The water temperature, if utilized solely for cooking, gets to 212 degrees Fahrenheit.


Here’s a great way to remember the difference—this analogy comes from a commenter from The Kitchn:

When I taught cooking classes I always told my students that a simmer was like an occasional giggle with the bubble occasionally bursting forth. But a rolling boil was like a full blown belly laugh. Students never forgot that analogy.
