West African Peanut And Sweet Potato Stew

The stew thickens from the sweet potato breaking down, not from any starch — leave it uncovered and let it reduce.

It should coat a spoon and still pour off it.

Peanut butter thins into the stock rather than sitting on top of it if you slacken it in a ladleful first.

The greens go in at the very end and stay green.
