In a heavy-bottomed pot on low heat add the cream, milk, vanilla seeds and bean. Whisk a couple of times and leave it to gently warm for 10 minutes.
Meanwhile add the honey, salt and eggs to a medium bowl and whisk together.
In a small bowl whisk together the cornstarch and 3 Tbsp milk. Set aside.
Once the milk and cream have steeped for 10 minutes fish out the vanilla bean and turn the heat up to medium. Slowly pour the egg/honey mixture into the milk mixture whisking vigorously all the while to incorporate it. Make sure you whisk so the eggs incorporate smoothly and don’t scramble.
Next, give the cornstarch mixture a quick whisk to make sure it hasn’t settled and add it to the pudding. Whisk a few times just to keep the bottom from sticking. Let the mixture heat until it begins to thicken, this should be the point just before it comes to a boil.
You can test if it is thick enough by dipping a spoon into it. If it coats the back of the spoon and stays there it is thick enough. Turn off the heat and remove the pot from the stove. Pour the pudding into the bowl you want to serve it in. Let it come to room temperature and then refrigerate for a few hours. It will thicken up further when cool.
