Sweat the onion in Roast Potato oil for 5 minutes on a medium/low temperature in a saucepan. Add the Veggie Rub No. 2. Cook 5 mins whilst stirring.
Increase the heat to high. Add the white wine and reduce by half. Then add the cider and reduce by half again. Add the veggie stock and marmite, herbs and maple syrup. Bring to boil then turn down to simmer for 20 mins or so. Stirring every so often.
Place in the oven to bake for 50 minutes to one hour, or until the loaf is completely firm on top. Check the loaf half-way through cooking and cover if browning too fast. Once cooked, allow to cool for half an hour before slicing and serving with gravy.
