To stare at someone (or something) so much that the other person feels as if you’re eating him or her…with your eyes. To look at someone with desire. A lot of it.
But this saying can also work with food. All the senses must be acknowledged and looked after when you’re cooking. If a really really good dish looks unappetising, you’ve failed at least half of your task. And if you plate a beautiful, spectacular looking dish…well, you’re already halfway to success.
This dish needs no explaining really. It’s not even a recipe, it’s just a gorgeous piece of edible art.
