A good apple corer should be a fast, easy tool for eliminating the core neatly. We found one that worked well.
Rather than slicing an apple into quarters and then removing the core and seeds from each piece, we'd rather reach for an apple corer, which does the job in one fell swoop. We tested five models and found out the task wasn't always so cut and dried. Narrow blade diameters—less than 3/4 inch—struggled to break through the firmer flesh on Granny Smith apples and forced us to poke and prod the core from the sharp metal teeth. The relatively stubby—3 1/2 inches or less—metal tubes on two other corers came up short when asked to plow through large apples. We had much better results with two other models; with testers preferring the one with the more comfortable grip.
