I have made this a couple of times & whilst it tastes amazing, I can't figure out why mine boils over!  I tried halving the recipe but it still boiled over. I then dropped to 100 and speed 2 but it then kept cooking for ages (about double the time) & never properly thickened up.
If so many others are having success with this recipe, can you please share the alternate cooking method that you are using to make it work without losing half of it all over your bench top?!
The flavour of this recipe is too divine for me to be able to give up on it!!
