Preheat the oven 180ºc fan.
Line a tray with baking parchment paper.
Mix the flour, yoghurt and salt together in a bowl.
Tip onto the worktop and lightly knead into a ball - don’t over knead or the bagels will be tough.
Divide into 4 equal pieces.
Make each piece into a ball and make a hole in the middle as wide as you can while keeping the bagel shape. The hole will close up as they bake so make it big before baking.
Place all 4 on the tray and brush with the egg and sprinkle the sesame seeds if using.
Bake for 20 minutes on the tray, and a further 5 minutes off the tray.*
Leave to cool for 5 minutes then slice and fill.
*While the bagels bake, put the bacon onto a separate lined tray and bake in the oven for about 15 minutes until it’s as crispy as you’d like it.
Fry 1 egg per bagel on a pan.
Bagel storage:
Keep the baked bagels in an air tight container in a cupboard for 3 days. They are best toasted.
Freezer: Baked bagels freeze really well in food storage bags for 3 months. Defrost for 1-2 hours on the counter then slice and toast.
