The recipe below is adapted from a Jamie Oliver gluten free and vegan holiday tart recipe using grams and milliliters instead of the cups we are more used to using. His recipe can be found at http://www.jamieoliver.com/recipes/vegetables-recipes/vegan-mushroom-chestnut-cranberry-tart/
Because most gluten-free all purpose flour contains potato starch, which is a nightshade, which I am better off not having, I made my own - used one cup in this recipe, and saved the other for another recipe. 1-1/2 cups brown rice flour, 1/4 cup white rice flour, 1/2 cup arrowroot powder, and a scant 1/4 cup corn starch.
INGREDIENTS
CRUST
1 cup gluten-free all purpose flour
1/2 tsp xanthan gum
1/4 cup soy-free Earth Balance buttery spread
1/4 cup coconut oil
1-2 Tbsp cold water
FILLING
1 large onion, finely chopped
2 cloves garlic, minced
5-6 carrots, grated
1 cup portobello mushrooms, sliced
1-1/2 cups cooked, peeled chestnuts, diced
2 Tbsp olive oil
1 tsp dried thyme
1 cup non-dairy cream cheese (I used Daiya, since it is soy-free as well as dairy free)
2 Tbsp garlic or walnut oil
1 cup white button mushrooms, sliced
2 Tbsp dried cranberries
1 small bunch flat-leaf parsley (optional)
GRAVY
1 Tbsp walnut or garlic oil
1 Tbsp redcurrant jelly
1-1/4 cups hot vegetable stock/broth
1 heaped Tbsp cornstarch or arrowroot powder mixed with 2 Tbsp water
COOKING INSTRUCTIONS
Preheat oven to 350 degrees Fahrenheit. Put baking sheet on top shelf in oven. Gather large skillet, small skillet, small saucepan, and tart baking pan.
Place flour, xanthan gum, buttery spread, and coconut oil into food processor. Pulse until makes small pellets. Add water and pulse until form dough. Remove dough. Kneed a few times. Form into ball. Place between two sheets of plastic wrap. Roll out with rolling pin - round and size of tart pan. Remove top layer of plastic wrap and flip into tart pan. Press into pan, repairing any places where dough tears or gets too thin. Set aside.
In a large skillet, heat olive oil. Add onions and sauté until soft. Add garlic, carrots, thyme, and half of the two kinds of mushrooms (reserving the other halves for the tart topping). Cook until all the mushroom juices are absorbed, about 10 minutes. Add the non-dairy cream cheese and half of the chestnuts. Salt and pepper to taste. Stir until cheese is softened and heated through, and all are mixed together well. Pour into crust in tart pan and smooth out. Place tart on baking sheet in oven. Bake about 40 minutes, or until crust is crispy done. Remove from oven.
While tart is baking: Heat 1 Tbsp walnut oil in skillet. Add remaining mushrooms and sauté about 4 minutes. Add remaining chestnuts and cranberries and sauté an additional couple of minutes.
Add 1 Tbsp walnut oil to small saucepan and heat. Add 1 Tbsp red currant jelly. Heat and stir until well mixed. Add hot vegetable broth and cornstarch/water mixture. Stir constantly while heating, until 'gravy' becomes good consistency.
Once tart is out of the oven, spoon the mushroom, chestnut, cranberry topping over it. Serve with the red currant gravy.
Jamie Oliver's recipe includes making roasted potatoes to go with the meal and the gravy.
