Sweet, nutty, with a kiss of citrus, black walnut maple sauce is an old-fashioned recipe perfect for serving on ice cream, with crepes, or soft cheese.
I love old cookbooks. Recently For research on lamb and goat recipes for the farm I work with, I’ve been collecting old Scottish and Irish books, most from around the 1900’s, since I know they historically work with lots of lamb and small ruminants.
An old-fashioned honey substitute
Aside from all of the great recipes like hotch potch I found, there’s been a few others that I knew would be keepers. Nut honey was one that caught my eye. At first glance it wouldn’t look like much, a little sugar, an egg yolk, some ground almonds—definitely not honey. What it seems like to me, is that it was likely a sort of honey substitute, maybe one for when honey wasn't available.
The inclusion of egg here is a good trick—one that I usually only see with old mustards, the type of ones in small bottles with artisan labels that have been growing in popularity, for good reason.
Egg yolk, gently simmered in a mixture with sugar and vinegar thickens lightly, giving a sauce with a velvety, custard texture. Without the added egg yolk, you'd be left with a watery, sugary syrup that's light in texture.
Having made plenty of stovetop mustard like I mentioned, I knew I could adjust the recipe to use maple syrup instead of sugar, as long as I reduced the maple syrup a bit to account for it's additional water content.
In place of the almonds, I used my hand cracked black walnuts, and the finished product is really good.
How to use it
The original recipe notes said that the nut honey was good for children as a tea time snack, but this one, a slightly thick, sweet, maple-walnut sauce, is a grown up version born to be spooned warm or cold onto all kinds of things.
I love it with creamy things like yogurt and ice cream, with soft cheeses, or tucked inside thin crepes with cream cheese. It’s a great recipe to try if you have a few nuts and some good maple syrup around.
Black Walnut Maple Sauce
Equipment
- Small saucepan, Metal mixing bowl
Ingredients
- ¾ cup maple syrup (½ cup brown sugar can be substituted)
- ¼ cup (2 oz) orange juice
- Zest of one orange
- Zest of one lemon
- 2 large egg yolks
- Pinch of salt
- ¼ cup (2oz) dry white wine
- 1 oz black walnuts lightly toasted and crushed
- ½ oz unsalted butter
Instructions
- Bring the maple syrup to a boil then turn down the heat and simmer for 5 minutes to reduce it by ⅓, then whisk with remaining ingredients. Don't worry about the butter, it will melt as the sauce cooks.
- Put the mixture in a metal mixing bowl above (not touching) simmering water, and cook for 20 minutes, stirring occasionally with a wooden spoon, until the mixture thickens and the egg has activated.
- Cool, cover, and refrigerate.
- If the sauce tightens in the fridge a bit, a splash of lemon juice will refresh it.

This recipe is excellent. The combination of maple, citrus, and black walnut is just remarkable. Great on waffles too. One of my absolute favorites, and just in time for black walnut season here in the Southeast.

Thanks Sam

This sounds delicious! I would love to try this with my harvest this year. Unfortunately, I'm allergic to eggs. Have you had success subbing the egg out with anything else?
Alan Bergo
Hmmm. You could use a little starch, that would do it too. Using egg in sauces like this is really old school, there's definitely different ways to do it, just don't thicken it too much.

Am I missing something in the recipe? I don't see how many black walnuts or when to add them to the syrup. Do you use 1oz, as in the original recipe? Also, can you tell me the volume of white wine to use? Thanks
Alan Bergo
Hey thanks, unfortunately I keep having problems with the recipe widget stripping things from source files. Everything's adjusted there.
Julia
thanks so much for your quick reply!
