Place water, oil, yeast, psyllium husk and 30g of the brown sugar into a bowl. Mix well and allow to stand for 5 minutes until mixture thickens.
Place Fate low protein all-purpose mix, cinnamon and sultanas into a separate bowl. Mix well and make a small well in the middle.
Add psyllium husk mixture to the Fate low protein all-purpose mix and, using your hands, mix until a dough is formed.
Knead dough for 3-5 minutes in the bowl. Cover with cling film and leave to proof for 30 minutes.
Once rested for 30 minutes - divide the dough into four equal amounts.
Pre-heat oven to 220°C/200° C fan/gas mark 7.
Shape each dough into a flattish ball, then take a wooden spoon and use the handle to make a hole in the middle of each ball. Slip the handle into the hole, then twirl the bagel around the handle to make a hole about 3cm wide.
Meanwhile, bring a large pan of water to the boil and add in the remaining sugar. Whilst waiting for the water to boil, line a baking tray with parchment.
Place the bagels into the boiling water - Cook for 1-2 mins, turning over in the water until the bagels have puffed slightly and an outer skin has formed.
Remove the bagels from the water using a slotted spoon and drain away any excess water. Place on the baking tray.
Bake in the oven for 25 mins until browned and crisp - the bases should sound hollow when tapped. Leave to cool on a wire rack.
Toast and top with butter as a tasty breakfast or snack.
