Perfect Way To Keep Your Hardboiled Eggs Intact
A great way to keep your hard-boiled eggs intact is to add a little bit of vinegar to the boiling water. This will help prevent the egg whites from seeping out of the shell as the vinegar raises the acid pH levels in the water.
The vinegar also helps with the peeling process as it breaks down the outer shell. Adding vinegar doesn’t change the taste of the egg, so you don’t have to worry about that. Next time try this method and add some vinegar to boiling water, as it is inexpensive and actually works.
