Orange Walnut Marvelade

• Marmalade
• 2 pounds oranges, well scrubbed
• 28 ounces sugar
• 3/4 cup sherry vinegar
• Spiced Walnuts
• 2 cups walnuts, chopped
• 1/4 cup reserved orange syrup
• 2 tablespoons sugar
• 1 teaspoon zest from half an orange
• 1 teaspoon ground ginger
• 1 teaspoon salt

1. Zest half of one orange and reserve for the walnuts. Thinly slice all oranges (I used a mandoline) and cut into quarters. Add to a large, wide pot and add water just to cover. You can soak for a couple hours or overnight.
2. Bring to a boil and simmer until oranges are very tender, 45 minutes to an hour. Add sugar and vinegar, turn heat to high and boil until mixture begins to thicken. Remove 1/4 cup for the walnuts. Continue to boil until temperature reaches about 212. You can also put a drop on a cold plate, wait a minute or two and see if it congeals. If so, you are done. Otherwise keep cooking a bit.
3. I canned mine, so I had a canning pot and jars ready. Just before adding to the canning pot, I folded in the walnuts (below).
4. Heat oven to 400 degrees. Toss walnuts in reserved orange syrup and remaining ingredients. Bake, stirring once for about 7-8 minutes, watching carefully. Let cool. Fold into marmalade.
