Once all of the stock is absorbed by the rice, add the chestnut puree, almond milk and brown rice miso paste. mix well until everything comes together and cook for 5-10 more until the mixture becomes thick and creamy. if the risotto ever becomes too thick, you can add a dash more almond milk.
Make the white sauce by placing the tapioca flour, lemon juice, nutritional yeast, mustard, almond milk and a pinch of salt into a large pan over a medium heat. cook until the mixture begins to bubble, continuously whisking to ensure the mixture stays smooth and doesn’t form any lumps. if the mixture ever becomes too thick, lower the heat and stir through some of the reserved pasta water to loosen up.
once the sauce is smooth, mix the pasta and sprouts through the sauce and spoon into a baking dish.
make the topping by placing the bread and 1 tablespoon of nutritional yeast into a food processor and blending until it reaches a bread crumb like consistency.
