Berries edible on Cotoneaster?

The berries are not considered edible on any of the Cotoneaster, though they are not toxic.

Some people think they are very tasty. They are related to apples and loquats, after all. I once tried a hawthorn fruit (related), it had the wierdest taste you can imagine, like an especially tart crabapple. It is an apple ancestor. Some say cotoneasters go especially well with venison.

Rowan berries are good too. And I have eaten osos for years, like the Gabrielenos. These are all relatives of the apple, the pear, and the quince.
