Macadamia Nut Soup
This comes from an older cookbook simply entitled The Polynesian Cookbook by Victor Bennett; it was first published as The South Pacific Cookbook, which is probably a better name for it, as it contains recipes not just from Polynesia, but also Micronesia, a few outlier island nations and, of course, Australia. Here is the super simple recipe for macadamias in soup! I've clarified the instructions a bit.
1/2 cup soft butter
1/2 cup whole macadamia nuts
4 cups chicken (or vegetable) broth
Salt and pepper to taste
1/2 heavy cream
1/2 cup additional macadamia nuts
1. Grind up the first 1/2 cup nuts into a fine powder and knead them in with the softened butter.
2. Heat the broth, whisk in the nut butter well, until smooth, season with cayenne, salt and pepper and heat thoroughly, whisking all the while. Meanwhile, chop the extra 1/2 cup macadamia nuts coarsely.
3. Add the cream, whisk well, and heat slowly. Serve hot with chopped nuts as a garnish.
