I used to make zucchini (courgette for the Brits and Europeans) bread with golden raisin and pecans. Forget what spices I used.
Was the only way I could get zucchini into my kids.
And I did a sweet potato souffle that had chopped pecans and marshmallow creme in it. And of course sweet potato pie. All ages ago. Left my recipe books in the US.
I just do baked sweet potatoes with a bit of cinnamon now. Much healthier.
