There are many eggplant varieties. One eggplant type is small, white, and looks a lot like an egg, another is long and skinny like a bean, while the “Toga” variety is yellow-orange with green stripes.
When choosing an eggplant, it should be firm and not too large. The length of a cucumber and the general circumference of a large pear should be about right. Smaller eggplants are less likely to be bitter (a bit of salt can help with this) and have fewer seeds, although these are edible.
