If you’ve ever needed to core a head of iceberg lettuce, either because you need to chop it up or you just want it easier to separate, there’s an easier way than trying to carve out the core or cut around it—just give it a good firm whack on the countertop, and the core separates easily, all by itself.
Just grab the head of lettuce firmly on either side and smack it on the countertop. Then turn it over and pull the now-separated core from the head of lettuce. You may need to wiggle it a bit, but it should give pretty easily. The video above shows you how it’s done.
