How to Make the Ultimate Umami-Bomb Vegetarian Demi-Glace
3/4 cup all-purpose flour
4 tablespoons unsalted butter
4 tablespoons cream cheese
1 teaspoon pure vanilla extract
1 1/2 pounds rhubarb, peeled if stringy and cut into 1/2-inch dice
1 pint strawberries, quartered
1 cup granulated sugar
1 tablespoon fresh lemon juice
2 teaspoons grated lemon zest
1 teaspoon grated fresh ginger
1 tablespoon crystallized sugar or coarsely crushed sugar cubes
Put the flour in a bowl and add the butter, cream cheese and vanilla. Cut or rub in the butter and cream cheese just until a dough is formed. Pat into a square, wrap and refrigerate for 30 minutes.
Preheat the oven to 400°. In a shallow 2-quart baking dish, toss the rhubarb with the strawberries, granulated sugar, lemon juice, lemon zest and ginger.
On a lightly floured surface, roll the dough into a rectangle about 1/8 inch thick. Cut the dough crosswise into 2-inch-wide strips. Lay the strips of dough over the fruit, anchoring them to the sides of the dish; trim if necessary. Sprinkle the strips with the crystallized sugar. Set the dish on a baking sheet and bake for about 45 minutes, or until the topping is golden and the fruit is bubbling.
