In a pot, add all the ingredients for the custard, except the
butter. Whisk all this together.
Place this onto medium heat and keep heating, while constantly
stirring, until the mixture thickens.
Take this off the heat and add the butter, mix until the butter
has melted into the custard.
Push this custard through a sieve to get out any lumps then
cover with cling film, making sure the cling film is touching
the surface of the custard.
Leave this in your fridge to cool down and thicken up a little
more.
In a separate bowl, add all the ingredients for the French toast
mixture. Whisk all this together until combined.
Place a pan onto medium heat and add some butter to it.
Get a slice of your bread and dunk this into the mixture. Let
this soak on both sides for about 30-60 seconds.
Take this out of the mixture, let the excess drip off, then
place this into your pan.
Cook until golden brown on both sides. Then take this out of the
pan and repeat with your other bread slices.
Putting everything together:
Get a slice of your French toast and place this onto a plate.
Add some custard on top of this, I used a piping bag to add the
custard but you can also just spoon it on.
Add some granulated sugar on top of the custard, you want to add
a thin layer. Then use a blowtorch to brûlée the sugar. Leave
this for about a minute so the sugar can crisp up.
Repeat with the rest of your French toast, then you can enjoy
it!
