Jayb there are lots of differnt recipes for it, a bit like Borsch, no right or wrong ones but no one agrees on which is right if you see what I mean.
Personally I prefer ones with smoked bacon or ham in , some just have the beans and corn in, some use limas and some use regular green beans.
This is what I make..
1 cup corn, I use fresh but you can use canned
1 cup beans , I prefer Limas but you can use half and lalf with regular beans or all green beans
2 tablespoons more or less of butter if bacon does not release any fat or you prefer not to use it
salt to taste, about 1/2 teaspoon for this size
1/8 the teaspoon paprika, I use my own ground Almas
1/4 pound of smoked bacon .
1 small onion ,chopped
fry the bacon, add then stir fry the beans and chopped onion, then add the corn and seasonings, toss around till the beans are cooked add a wee bit of moisture if you need to but don';t add too much ,
there are variations which turn it into a soupy stew but I like it more like a side dish.
You can add a bit of red pepper for colour, a pinch of sugar is corn is not so sweet.
I have a Soul food recipe that is interesting which makes it more soup like, it adds chicken stock, potatoes and okra but I think that is not true succotash and have never done it that way.
Basically it is corn and beans with whatever you fancy adding in..but not sloopy. Mine is different all the time
