Method
Put the onion, olive oil and butter In an ovenproof, wide casserole dish. Fry over a low heat until the onion is soft and beginning to turn golden brown. Stir in the flour and mustard powder and cook, stirring, for 2 minutes. Gradually stir in the apple juice, followed by the stock, then the wholegrain mustard and bay leaves. Bring the sauce to a simmer.
Add the celeriac and leek and continue simmering for 15 minutes, or until the vegetables are almost tender. Take off the heat and remove the bay leaves. Stir in the spinach, followed by the beans and tarragon. Season to taste. Preheat the oven to 200C/180C Fan/Gas 6.
For the dumplings, mix the flour and baking powder in a mixing bowl. Rub in the diced butter until you can only feel small lumps, then stir in the tarragon and salt. Mix the yogurt with 2 tablespoons of cold water, then drizzle over the flour and mix quickly to form a sticky dough. Flour your hands, then quickly roll into 12 balls.
Arrange the dumplings on top of the bean stew. Cover the casserole with the lid and bake in the oven for 10 minutes. Remove the lid and bake for 15–18 minutes more, or until the dumplings are puffed up and just turning golden brown on top. Spoon into shallow bowls to serve, scattered with extra tarragon if you like.
