I toasted the coconut and
walnuts by spreading out in an even layer on a foil-lined cookie sheet, baking at 350 degrees for about 5 minutes, then stirring with a rubber spatula and baking for about 2 minutes more. It’s easy to overbake/scorch the coconut and
walnuts, so keep a watchful eye on them. If they start to become fragrant, take them out of the oven.
