How to Make the Ultimate Umami-Bomb Vegetarian Demi-Glace
2 pounds red and white seedless grapes, cut into 20 to 25 clusters
3 egg whites, lightly beaten
1/4 cup sugar
1/4 cup cold water
2 bottles dry red Zinfandel
1 bottle blush Zinfandel
1/2 cup (4 ounces) sweet vermouth
1/4 cup (2 ounces) dry vermouth
1 cup (8 ounces) peach brandy
1 cup (8 ounces) Bacardi Limon
1 cup (8 ounces) cranberry juice
1 block of ice
4 cups thinly sliced fruit, such as peaches, pears and red apples
Seltzer, for serving (optional)
Line a large baking sheet with wax paper. Holding each grape cluster by its stem, dip it in the beaten egg whites and sprinkle with sugar. Arrange the clusters, without touching, on the baking sheet and freeze until solid (or for up to 1 week).
In a large bowl, combine all of the ingredients and mix very well. Refrigerate overnight.
Pour the punch into a chilled punch bowl. Add the ice block and scatter the sliced fruit on top. Hang the sugared grapes around the edge of the bowl. Serve the punch in cups with a splash of seltzer and a cluster of grapes in each cup.
