There are lots of food trends and fads. Some foods become more popular over time; other decrease in popularity. Prunes are a food that were much more popular a hundred years ago than what they are now – though personally, I like them. So when I saw a recipe for Prune Souffle in a 1924 cookbook, I decided to give it a try while recognizing that prunes are not trendy.
The Prune Souffle didn’t puff up like the typical souffle. It was very rich, and contained chopped walnuts which added a nice crunch. The dominant flavor was the prunes, though there was a hint of cinnamon. I’m not sure exactly how I’d rate this dessert. It’s definitely different than what I expected, and it’s richer than I’d like; but in an old-fashioned way, it was tasty.
Here’s the original recipe:

I’m not sure why the souffle did not puff up. It called for several fairly heavy ingredients – the chopped nuts and prune puree which may have weighted it down. Also, since the old recipe calls for a “slow oven,” I baked the souffle at 325° F. but maybe it would have worked better if it had been baked at a higher temperature.
When I made this recipe I wasn’t sure how many prunes were needed to get 1 cup of pulp, but I estimated that I’d need about 1/2 pound of prunes. I cooked the prunes for about 30 minutes get them nice and soft, and then put them through a Foley Mill. (Another option would be to puree them.) I ended up with a little less than 1 cup of pulp, but went with it.
Here is the recipe updated for modern cooks:
Prune Souffle
1/2 pound prunes
water
2 eggs, separated
1/2 cup chopped nuts (I used walnuts.)
1/2 cup grated bread crumbs (I grated 1 slice of bread.)
2 tablespoons sugar
1/4 teaspoon salt
1/6 teaspoon cinnamon
1 tablespoon lemon juice
grated rind of 1 lemon
Preheat oven to 325° F. Put prunes in a saucepan and cover with water; bring to a boil then reduce heat and gently simmer until soft. Remove from heat and drain; reserve 1/2 cup of the prune juice. (If there is less than 1/2 cup of prune juice, add water to make 1/2 cup.) Puree the prunes or use a Foley Mill to press through a sieve. Set aside.
Beat egg whites until fluffy and stiff. Set aside.
Put the chopped nuts, bread crumbs, sugar, salt, cinnamon, lemon juice, grated lemon rind, pureed prunes, 1/2 cup of prune juice, and egg yolks in a mixing bowl; stir to combine. Fold in the beaten egg whites. Put in a 1-quart baking dish, and bake until the top is lightly browned and starting to crack (30-40 minutes). Can be served warm or cold.
