Burnt Butter Microwave Siphon Cake

This is probably one of the most technological recipes that I've written up so far. The only unusual equipment it only requires is a microwave and a gas siphon, but I think it's a worthwhile trade-off for near instant cake.

Ingredients:

1. 65g butter
2. 3 eggs
3. 30g caster sugar
4. 4g salt
5. 35ml milk
6. 105g flour

Method:

1. Put the butter in a small saucepan and melt over a low heat.
2. Simmer the butter for 5 minutes, stirring frequently. This will cook the proteins a bit, giving them a nutty flavour.
3. Allow the butter to cool.
4. Mix the other ingredients in a bowl with a whisk and then add the butter.
5. Whisk well and then pour into a 0.5 litre whipping siphon.
6. Charge the whipping siphon with once charge of nitrous oxide and shake well.
7. Chill the whipping siphon in a fridge.
8. When ready to serve, put three holes in the bottom of a plastic or paper cup with the sharp point of a knife.
9. Fill the cup one third full with batter from the whipping siphon.
10. Microwave for 40 seconds.
11. Remove from the microwave. Count to ten and then turn the cups upside down over a plate to remove the cake.
12. Enjoy with a fruit coulis or on its own.

Makes 20 cups worth of cake (which is a phrase I never knew that I'd ever write).
