A real classic Sinterklaas recipe is this variant of "Taai-taai".
* 180g buttermilk
* 180g maple syrup
* 100g honey
* 50g concentrated apple juice
* 50g rice malt syrup
* 700g rye flour
* 1/2 table spoon of natriumbicarbonate (NaHC03)
* 2 table spoons of anise seeds
* 2 eggs
Mix the buttermilk with the sweets and the anise seeds, and heat slowly, making sure it does'nt get hotter then hand-hot (~35 degrees celcius). Let the mix cool down. Put the flour in a large bowl and mix the natriumbicarbonate and the eggs with it. Add the cooled down fluid and mix with a wooden spoon till you have a sticky dough. Close bowl with some plastic and let it rest for 24 hours.
Make figures from it around 1.5 cm thick and bake for 30 minutes in a 175 degrees celcius oven.
