1 Put the water in a medium sized saucepan with the butter and thyme then simmer till the butter has melted.
2 Tip in the flour and beat as hard as you can until the mixture pulls away from the side of the pan and is lump free.
3 Transfer into a bowl and spread up the sides of the bowl so it cools more quickly. (If you have a stand mixer use this bowl).
4 Add the beaten egg, little by little, until the mixture looks like a batter and becomes amalgamated. You may not need to add all the egg.
5 Crumble in the cheese and fold everything together then chill the mixture for a little while.
6 Heat the oil to 180 degrees in a large pan; if you have a deep fryer all the better. A sugar thermometer is invaluable if you don't have a fryer, and always err on the side of caution when you are cooking with hot oil.
7 To check if the oil is ready, drop a piece of bread in to see how quickly it colours.
8 Drop in teaspoon sized blobs of the mixture in batches and cook for three minutes or so each.
9 Eat crisp and hot from the pan with some apple syrup drizzled over the top.
