Using a paring knife, cut the ends off. Do not cut too much off the tip as you want to be able to maintain the shape. See note 1.
1 Zucchini
Place the tip of the corer into the center of where the opening will be (this is where the zucchini was attached the stem and not the flower, which is the larger end) See note 2.
Gently start turning the corer using slight pressure to push into the flesh. Move the corer as if it were a screwdriver to push into the zucchini whilst rotating the vegetable. See video.
As the flesh is carved out, pull out to remove flesh and collect into a bowl. Clear any buildup on the coring wand. As the opening gets bigger, the motion will become more like carving and you will move the corer around the inner perimeter scraping flesh out. Visually check the inside to know where more needs carving and where flesh may need to be scraped out.
Repeat step five, until there is no more flesh, every so often shaking out any loose flesh. Leave a perimeter of about 3mm of skin.
